While working as a migrant worker in New Mexico, Kimble becomes an unwilling party to the kidnapping of a young boy who is the son of his landowner boss. The boy, Jimmie, has been abducted by Ralph Simmons, a disgruntled former football player, along with his wife Helen and his cousin Dave. When Kimble discovers that Jimmie is a haemophiliac and that Ralph has bruised him during the abduction, Kimble must find a way to get the boy away from the kidnappers and to a hospital, or Jimmie will soon die from internal bleeding.
