On the first day of Tenth Grade, Lee Ping is framed for a mind blowing prank and thus is sentenced to one full year of detention and one full year of grounding. Lee's fellow inmate Biff convinces him to sneak out of detention to collect evidence from the auditorium which can prove his innocence. The only thing Lee can salvage is a camera phone which contains a picture of someone messing with Lee's bag during the Prank, and when Lee finds a match for the hand in the photo he will clear his name.
Having collected a photo of the hand of suspect number one Lee enhances it and discovers that the suspect is wearing a A. Nigma High championship football ring and has a scab on his mid knuckle. Realizing that the scab could be gone by tomorrow Lee sneaks out of detention again and tries out for the football team so that he may check the players for scabs. Lee soon discovers that their water boy is a kleptomaniac who stole the ring and a can of paint from Lee's bag.
Having failed to find the prankster on the previous day Lee is at a dead end. Luckily Lee encounters a group of students known as the Skaters who state they were responsible for the paint portion of the Prank and request instructions on more pranks from Lee. Misunderstanding Lee's intentions they plot to rig the Student of the Week vote to come up as Principal General Barrage and dump the remaining paint on him on live TV. Lee is narrowly able to avert the disaster and in the process learns the email address of the prankster, Radcircles@ANigmahigh.
A Chance encounter with his old rival, Irwin of the Mathletes, leads Lee to the conclusion that he is Radcircles. Lee sends Holger in during detention to spy on the Mathletes but he is captured and tortured forcing Lee to sneak out to rescue him. Lee confronts Irwin and the latter reveals that while he did send a email to the Skaters, and then some, it was a photoshopped image of himself and Lee to make it look like the latter was picking his nose. In a subplot Cam is attempting to learn the identity of the one who sent the photoshopped image and in the process learns the identity of Radcircles, former principal of A. Nigma High, Principal Wurst.
Lee is blackmailed by his self proclaimed girlfriend Brandy who forces him to attend a party of hers or else the fact that he's been sneaking out of detention will be revealed. In order to avoid the wrath of his overbearing mother Lee attends the party. There he learns the identity of those that composed the music for the Prank, the Dudes of Darkness, which has a hypnotic effect on the other party goers. Unfortunately Lee's mother learns from watching the news that Lee was at the party against her strict demands of grounding, getting him into even more trouble.
Following the events of last Friday Lee is going to see the Dudes of Darkness to Question them about the Prank. He learns that Cyrus recorded the music during the prank has become consumed by the hypnotic effects of the music becoming obssessed about it. Under the hypnotic effects of the music Cyrus quits the Dudes of Darkness. Biff, easily their biggest fan, is furious with Lee and promises retribution if he fails to reunite the band. Lee uses Barrages voice to snap Cyrus out of the trance in time for him and Lee to blow the crowd away at the battle of the Bands. Once home Lee contemplates listening to the Music to learn any information about the Prank, fearing that he might become consumed by it like Cyrus was.
A Nigma High is consumed by a Flu Epidemic, Lee included. Lee's cell phone containing the Prank Song is stolen by the Tazelwurm. Lee chases the Tazelwurm to a underground laboratory, where he learns the Prank Song was developed there. The Tazelwurm gives Lee a folder containing all the information about the Prank.

Facing off against Radcircles in a bizzare game of Cat and Mouse Lee attempts to use the email to contact Radcircles during the play to make him reveal himself unsuccessfully. Brandy, Lee's leading lady, becoming frustrated with Lee, rips his fake beard off, nearly revealing to the crowd his identity. Luckily Biff and Camilio manage to cover for him, and in the process Lee gets back to detention before Barrage dismisses him. While Lee has failed to find Radcircles, he vowes to him in a email that he will find him.
Lee is given one day of amnesty from detention as per the rules of the Students charter of rights. But he can't enjoy the day off as he's accidentally incured the wrath of the fearsome 15th graders when he enters their territory chasing a lead. During the brief period of time in which the Tazelwurm had Lee's phone someone programed in a series of numbers, a locker number and combination. Inside said locker Lee finds his original bag from the day one prank. However Lee has more pressing matters to attend to, he must deal with the 15th Graders or else they will daunt him for the rest of his high school life.

In a side plot Lee discovers that the Tazelwurm planted a key like device inside his bag which proves vital in the group's survival, and it's discovered that not only did a trio of environmentalists release the frogs at the school and trigger the melt down but they also released them during the Prank, though they aren't connected to the others in the conspiracy.
On a particularly rainy day Lee is surprised to find Holger arriving at school dry as a bone. He explains that during the events of "Friday Nights Bites" Holger discovered a series of underground tunnels connecting the school and Brandy's apartment. Lee makes his way to the library where the tunnel entrance is suppose to be, though he locates the entrance the fire alarm is pulled forcing Lee to evacuate. The Alarm was pulled by a fan of Lee's work Lynch who ends up in detention with Lee and Biffy. Vice Principal Victoria is planning on renovating the library thus preventing Lee from investigating the tunnels for 2-3 weeks, forcing Lee to allow Lynch to tag along to the tunnels. Once inside Lee finds his father's office and collects a photo of his family in Korea shortly after he was born, though when Lee and Lynch bring Tina back everything is gone.

Radcircles has a plan to get Lee expelled, to this end Lee is forced to send Camilio in undercover. Camillio discovers that the group is planning a trio of pranks against the staff of A. Nigma high that will unquestionably frame Lee, but it's discovered too late that this is a distraction for the group to steal Barrage's leg and plant it in Lee's locker. Lee and Holger are able to work together to leave the leg somewhere Barrage can find it but away from suspicion.
Tina runs a embarrassing story on the news in which it's revealed that the Glamazon's are actually bald and wear hair extensions, prompting Lee to suspect that they will be seeking revenge. Lee sneaks out of detention and goes to the mall to protect Tina in the process discovering that a bag exactly like his was purchased at the mall. Lee is able to call in Zed to distract the clerk while Holger sneaks in and steals the store's security footage. Lee is able to prevent what appears to have been a attempt by Brandy to poison Tina but in reality is a elaborate scheme to break up her and Brad Von Chillschene. Lee is able to hitch-hike his way back to school in time to be dismissed by Barrage. While at home and after watching incredibly large amounts of footage Holger discovers that the only person to have bought a bag like Lee's was none other than Camillio! In a subplot Biffy reconciles with his childhood friend, Kimmie McAdams, while in Detention.
Following last episode's cliff hanger Holger has yet to tell Lee about Camillio for fear of breaking up their friendship, instead coming to believe Camillio has been replaced by a robot and setting out to expose him. Lee has more pressing matters to deal with, having discovered that Chaz stole the Prank footage from Day one and is planning on airing it on his upcoming "Chaz's Corner" segment, which contains evidence of his innocence. Barrage begins hunting down the footage promising rewards for anyone who can bring him the Prank Footage. Lee is able to convince Chaz to air the footage early so that he can watch it, discovering that it was Camillio who switched his bag! At home Lee tries to confront Camillio with the information but is interrupted. He does, however, tell Radcircles that he knows that he's Camillio, who only begins laughing maniacally.
His popularity has slipped and Cam is now in the cool crowd. Chaz get suspended from the news desk. However, Vice Principal Victoria is attending the party to talk with the grown-up. Lee manages to steal one of Cam's shoes but couldn't make it back to detention, since Barrage knows that he sneaks out of detention, unaware of the air vents. Unexpectedly, Vice Principal Victoria picks him up, spares him for sneaking out of detention and drives him back to detention, she tells Barrage that she let him out so he can help her carry books and tells Lee not to let it happen again. Lee finds out that Cam's shoes fit the shoe print from the rafters, unfortunately for him, Holger and Cam aren't speaking to him again, since they think he cares more about the prank and the mysterious Radcircles rather than them. Cam clams that in the prank Lees bag fell and he put back up on the chair. He also told Lee that he brought a bag like Lees because it looked cool, and when Lee had the same one he gave it to his sister. Lee is still unsure whether Cam was hypnotised during the prank as he acts like a monkey when someone says 'butterscotch' so he might have been hypnotised.
Holger forces Lee to run for president because he thinks it will get even with Lee and Cam. When Lee hears that if he wins he can get out of detention for good, he takes the vote seriously. Biffy helps Lee humiliate Cam as Kimmie helps Cam humiliate Lee, Holger makes everything worse by accidentally making Cam think about tell everyone about Lee's crush on Tina Kwee during the vote.

Lee, Biffy and Holger pursue him throughout the school but he escapes, giving Jenny, who is now smitten with him, another ride. During their webcam conversation, Cam suggests the Serpent's gathering of things from Lee's family is related to cloning, or perhaps the Serpent is simply a fan.

As a surprise, the Serpent arrives and gives Jenny her bike back after it was lost and they go on a ride together to make up for him leaving her afraid. Grayson arrives at Cam's place to apologize for blackmailing him and the others for bullying him when they were younger.

The episode ends with Tina, upset that she can't further her relationship with Lee due to the pact.
Brandy tells Cam the "Glamazon Vote", where they vote for a leader, is today and turns down his offer of help due to his reputation declining after losing his presidency. Biffy figures out a way he and Lee can figure out if cloning teachers is taking place: talking to the the 15th Graders. The 15th Graders build Beth a trebuchet for her, due to Chopper being attracted to her. Biffy pretends to set up a date after school for Chopper in exchange for some information, some photos of a teacher's weight fluctuations further convincing them of the cloning. Lee and Biffy decide to go to Brandy's apartment building to find the teachers.
