Secret Agent Bert Morris is sent by his superior Colonel Lancaster on a dangerous mission. He must parachute into East Germany to rescue Paula Krauss, the daughter of a now deceased scientist who had successfully developed a death ray and it is believed that Paula has his knowledge of how to create the device. In addition to Morris being up against the Soviets and East Germans, the Red Chinese have entered East Germany to bring back Paula and her knowledge to their homeland.

After seeing off Morris, Colonel Lancaster goes to a clinic to get a state of the art glass eye implanted into his nerves so Lancaster can move the prosthetic eye in a similar fashion to his good eye. What Lancaster doesn't know is that the clinic is run by Communist agents. They have placed a miniature camera into the prosthetic eye that will act like a television camera allowing the Soviets to see what the intelligence chief Colonel Lancaster can see.
