Petruis and Collins are members of an expedition tracking a strange ape species through unexplored jungle. When Collins kills one of the creatures, the party agrees that it's time to retreat back to civilization. Jealous of Collins' success, Petruis hatches a plan to lure in another ape--but just as Petruis is underestimated by his companions, he may be underestimating the very environment he seeks to pillage.
