A Russian colonel codename Patch One is out to get revenge for the killing of his brother by Murph, a U.S. Intelligence agent. He kidnaps Murph's son and takes him to Cuba during the missile crisis in the 1960s. Murph is on his way home from the Aleutian Islands when the kidnapping occurs. He and his wife Tatina give chase and finally rescue their son after working their way onto the island as interpreters. Murph leaves for the island first, encounters Castro's brother Raul, and works his way into his confidence. Murph had to make a second trip back to the island after rescuing his son and bringing the Cuban partisans who help them retrieve their son back to the States. The chase leads through South Carolina where Murph encounters the assassin of President Kennedy, who helped the colonel kidnap the boy. A beautiful Russian agent assisted him.
