Animal Protector plot
A thick fog hangs over the island on which a military base and a medical scientific center are located. Officially, important medical research is conducted through animal experiments, but in reality it is an illegal investigation into bacterial warfare. The island is guarded by a platoon of soldiers led by Colonel Whitlock. They are called the scum of the army and because they are obliged to spend their time here in the service, they want revenge. When they announce that the island is infected with a dangerous infectious disease, not only the suspicious government but also a group of animal protectionists take action.
