The Bride and the Beast

Dan Fuller, a big game hunter, is forced to kill his pet gorilla when it attempts to rape his new bride Laura. The woman starts to experience strange urgings following the encounter, and submits to hypnosis under the care of a psychiatrist. She reveals to her shocked husband that she was actually a gorilla in a previous life. Slowly she reverts to her former bestial self, and winds up eloping into the jungle with a male ape, with her cuckolded husband staring helplessly after them.
