Aurelio Casillas is a smart kid with big plans. He seeks to work with Don Cleto, an alleged dangerous criminal. His dirty dealings constantly put him at odds with Police Captain Jiménez.
Aurelio drops out of school to smuggle Don Cleto’s merchandise and he decides to work with the boy. In an attempt to impress Ximena, his new boss’s daughter, Aurelio puts on a dangerous display.
Aurelio’s first job ends up with him lying on the floor, but it’s clear that he’s got some good ideas. Don Cleto, who only sees him as a gutsy little boy, decides to reward him.
Aurelio witnesses a mysterious exchange between Eladio, Don Cleto’s right hand, and a local boxer. Now Cleto must make a deadly choice between Eladio and Aurelio.
Don Cleto puts Aurelio’s loyalty and ideas to the test. Police Captain Jiménez tries to guess what the boy is up to, but all he wants to do is catch Ximena’s eye.
Aurelio convinces El Taladro, boxing coach and aviator, to take him in as a mechanic and pilot apprentice. Meanwhile, the police and his wife leave no stone unturned in their search for Eladio.
Police Captain Jiménez teaches Aurelio a gruesome lesson. He knows who the kid is working for. The Police Officer gets close to Angélica, Don Cleto’s wife. Aurelio meets Amado, his half-brother.
Angélica and Captain Jiménez meet again, but they’re not as careful as they think. Now that Aurelio has money, he spends it on his mom and Ximena. He earns Amado’s trust.
Aurelio encourages Angélica to pay more attention to her daughter and warns her against seeing Captain Jiménez again. The boy makes the most of his time off and asks Ximena out.
Jiménez has the evidence he needs to charge Don Cleto with Eladio’s death. Angélica discloses his location, but the town is full of spies. Aurelio learns how to shoot. Ximena, on the other hand, is a seasoned pro.
The police case falls apart: the weapon does not match the murder bullet. All Jiménez can do is watch as his car turns into ashes. And he knows who’s behind it.
Don Cleto has Angélica followed. The information he gets in return catches him by surprise. Aurelio takes off as aircraft captain for the first time ever. Jiménez is waiting for him as he lands.
Jiménez is hot on Aurelio’s heels, so Don Cleto decides to send the boy off to the United States. Upon returning, six years later, the first thing he does is visit the last place he went to before he left.
Aurelio returns with fresh ideas to take the business further, but Jiménez doesn’t forget the car incident and threatens him. Angélica warns Ximena about the importance of choosing wisely when it comes to men.
The new business’s mission nearly fails because of Jiménez. Don Cleto won’t put up with him anymore and Aurelio volunteers to take care of it. He’s ready to confront the Captain.
