When Clover and her friends meet a mysterious witch in the woods, she invites them into her cabin for some tea. But unbeknownst to the group, the witch has ulterior motives.

After drinking her secret potion, the trio suddenly becomes groggy and one by one begin morphing into half-human, half-animal creatures. First Jessop transforms into a centaur, then Tara morphs into a sphinx, and finally Clover changes into a gorgon.

While the witch watches the beasts circling one another and begin mating, the three explorers are oblivious as to what's happening to them. When they return to their original form, the witch transforms into a three-headed hydra, binding them together with her tail while giving them a new kind of simultaneous climax.

By the time the group leaves the witch's cottage, their only memory of the event is a strange ache in their lower extremities...
