A full scale riot takes place at the Prison and Jo is taken hostage. Meanwhile, at the World Peace conference, the Chinese delegate's aid prepares to kill the American delegate.

The Master is behind the Keller Machine and uses it to recruit the rioting inmates at Stangmoor Prison. He plans to capture a missile and fire it at the World Peace Conference.
