Jack, son of Hades, has to guard Jill, the youngest daughter of Zeus, with his life, or he will die by a curse. When the two of them appear on Equus with Jill trapped in Jack's body, however, things may get very complicated for the duo.

With the two of them trapped in a world filled with sentient, colorful ponies, Jill may be able to find the peace and happiness that she has always longed for. For Jack, though... that may be a different story.

Forced by Jill to not kill any of these inhabitants, how will Jack be able to cope with this world? Or better yet, how will this world be able to cope with Jack of all people?
