Bergerac (1981)

S5E5 The Deadly Virus

A group of animal rights activists launches a daring operation to liberate four monkeys from a scientific research facility. Unbeknownst to them, one of the primates carries the highly contagious marbury virus. As the monkeys escape into the wild, the potential outbreak poses a grave threat to both human and animal populations, prompting a race against time for health authorities to contain the situation before it spirals out of control.
