At Castle Grayskull Adam, Teela and Cringer are visiting the Sorceress when they are suddenly contacted by the Silani. They inform the heroes that Baron Grod is planning to hunt down the last remaining unicorn on Eternia. Adam, Teela and Cringer fly out to Baron Grod's castle and plead with him not to go through with the hunt. Baron Grod refuses, forcing Adam to seek the assistance of his father.
But before they get back to the Royal Palace Baron Grod orders his Ogre comrades to capture the heroes. Taken to the Ogre's lair the three of them escape with Adam and Cringer transforming, whilst Teela evades the Ogres who pursue her. He-Man, Battle Cat and Teela arrive in the Whispering Valley to stop Baron Grod from capturing the unicorn, but are too late.
They travel to Baron Grod's castle and during a battle he accidentally resurrects one of his other captured animals. The animal attacks him, but Teela save his life. This prompts Baron Grod to free all the animals he has captured and the last remaining unicorn.
