Prince Adam is trying to relax. Upon spotting Zoar and suspecting trouble, he becomes He-Man and races to Castle Grayskull. There, the Sorceress reveals the Eye of Eternia, which can detect any foe in any dimension. It shows them Skeletor, who has passed into another dimension and found the Cosmic Clock, allowing him to control time. He uses his dark magic to pull the Sorceress through the Eye into his evil clutches. He-Man enlists the aid of Orko, who sends a group of heroes into the Eye to face Skeletor and his minions. Skeletor must be stopped before the clock strikes 12, or he will be able to control time. During the fight, Battle Cat frees the Sorceress from her glass prison, and He-Man grabs the clock's pendulum before striking 12. The clock explodes, but Orko whisks the heroes to safety in the nick of time.
