Three well-meaning animal rights activists, including Kim's boyfriend Kevin, liberate three monkeys from Gaines' research unit, unaware that one has the deadly Marburg virus. It bites Kevin and also attacks a holidaying couple. Jim and his team must hunt the animals down without putting the whole of the island in a panic but after Kevin dies and the monkeys are caught, one of the activists, possibly infected herself, goes on the run.
