Link

Dr Steven Phillip lives in a Victorian mansion by the English Coast with three chimpanzees whom he has been doing research on to investigate the “link” between man and ape. Jane Chase is invited to his house during summer vacation as an assistant, and upon arriving, she gets greeted at the door by a chimpanzee named Link, dressed in a butler's uniform.

Philips disappears, but Jane thinks he left for London. She decides to stay with the chimpanzees. Over time the chimps become more violent. They begin to take over the house and to get involved in inter-tribal squabbles, leading to a confrontation with Jane.
