Soon after discovering an old family heirloom called The Necklace Of Argon, Tracey and her brother Wayne are magically transported to Blizzard Island where they set off on a quest to find the Great Argon and help save that world and ours from dying.
Tracey and Wayne's quest leads them to the Battlefield of The Gods, a barren boulder covered wasteland where magic does not work. With the help of a strange creature named Clea our heroes once again thwart Sydney the Witch's plans to steal the necklace of Argon and continue on their journey.
Their journey is made very difficult when our heroes are confronted by Sydney the Witch and Sir Python as they attempt to cross Fool's Bridge.
While Looking for the Great Argon Tracey, Wayne and Rog enter the Thicket Of Night where they are taken prisoner by the NightCrawler, a slimy creature on eight legs who makes them his slaves. Finally with the help of a bumbling Sydney The Witch who is after the huge deposit of Bhok crystals that resides in the Thicket, our heroes manage to escape.
Sir Python and Molcaster devise an elaborate plan to lure our heroes into their lair by setting out fake Argon foot prints using an old bedroom slipper of Argon's that they found. Wayne is the only one that falls for the snake's plan and is captured. Now with Wayne as Sir Python and Molcaster's prisoner they have but to wait for Tracey and Rog to come to rescue him and trap them as well and steal the necklace of Argon. However, with the help of some exotic instruments sent to Tracey and Wayne from their Father, our heroes charm their way out of danger.
While exploring the caverns of Hollow, Hollow our heroes meet two strange creatures named Bang and Clang, the Bellringers of Argon who are joined by a single white beard. The two constantly argue with each other over everything and can't stand each other anymore. After Tracey separates the two by cutting their beard the Bellringers are eternally indebted to Tracey, Wayne and Rog which is more than the trio can handle.
After curing Molcaster of an itching problem (Thanks to the Witch) the healing Stone gives Tracey clues about Argon which lead her to the Witch's lighthouse to find talking stones. Tracey and Rog are able to get more information from the stones and escape before Sidney and her super power potion capture them.
During an eclipse Tracey, Wayne and Rog must get to the top of the highest mountain on Blizzard Island to find the Great Argon. Unfortunately, the eclipse affects everyone in strange ways including making Rog extremely love sick for a female Rogalonian and switching Sir Python and Molcaster's personalities.
All of Blizzard Island is frozen with fear as the legend of the last leaf falling to the ground will start the winter that has no end. If that happens then all on Blizzard Island will freeze over forever. Tracey and Wayne show up but can they save the day and return life to normal on Blizzard Island?
Eggbert realizes that Sidney truly misses him and that more surprisingly he misses her.
Tracey, Wayne and Rog make it through the Vale of Fears and discover the Well of Dreams, the sleeping place of the Great Argon. However, hot on their trail are Sir Python and Molcaster with Sidney the Witch pulling up the rear.
Our heroes are finally able to wake the Great Argon and return the necklace to him. In doing so we learn the real meaning of the quest and we also learn that the true quest is yet to come.
