Beth is desperate for Liam to finally confess his romantic intentions. Desperate enough to recruit her best friend, Jessie, to hike into the woods with Liam and his friend David. When they reach a strange glade filled with statues of stone animals, the hike becomes something altogether strange. The four hikers begin to change, taking on animal traits as they try to get out of the forest.
As they wrangle their emotions and feelings for one another, the four unwittingly stumble into a very old magical trap. The only way to out is by fueling the power of an imprisoned god, a power which feeds off the primal sexual urges thriving in the four young travelers.
