American scientist John Hathaway (Gregory Peck) goes to Communist China on a mission to steal a formula for an experimental agricultural enzyme with enormous practical benefits. Those in charge of the mission implant a microchip in his brain that will allow him to communicate with them. However, Hathaway is unaware that the device monitors his activities -- including playing ping-pong against the Chairman (Conrad Yama) -- and can be activated to kill him if his mission doesn't succeed.
