On a school trip, practical jokers Paul and Alex plan a prank to scare the girls, but it goes disastrously wrong when Paul vanishes into thin air. While his friends search in vain, Paul finds himself lost and alone in a strange place.
In an abandoned Spellbinder castle, Paul and Correon learn that the darkness was caused by over-ambitious Spellbinders. Realising that Paul's knowledge is too dangerous, Correon agrees to help Paul return to his own world.
Distracted by a world that is entirely new to her, Riana finds herself lost in Sydney. Believing that Paul is suffering from exhaustion and amnesia, his father assumes that Paul has imagined his story about the Spellbinders and Riana.
Captured by the Summoner, Paul must convince Riana's mother to help him escape. In a last effort to stop Paul, Ashka damages the Summoning Tower, and Paul is forced to take Riana with him as he finally makes his way back home.
As Paul starts to learn more about his new surroundings, he begins to suspect that he has traveled back in time, until he sees Ashka demonstrating the Spellbinder's power.
Paul, Alex and Katrina set out to rescue Riana, but a nosy neighbor calls the police who catch Alex and Katrina. Paul shows his father the video of Ashka and introduces Riana, finally convincing him of the truth.
The race is on to rescue Christine and get the flight controller before Ashka gets there. With help from Alex and Katrina and even Katrina's mother, Ashka is finally cornered and defeated.
Alex and Katrina find a way to get back to the cave, by buying places on a school literature camp. Paul agrees to make gunpowder for Gryvon but hides the real recipe from him. Riana turns to Correon for help in rescuing Paul.
Ashka challenges Correon to a duel and sabotages his power suit to ensure that he loses and will be banished. Paul must learn to operate one of their flying ships in order to escape the castle.
Riana is injured trying to get away from the authorities and at the hospital, a psychiatrist takes an interest in her. Paul tries to recharge the power suit to convince his father that he's telling the truth.
