While working as a gardener on the estate of a wealthy couple, Mike and Laura Pryor, Kimble is mistakenly abducted by Harold and Irene Cheyney. Harold is a Korean war veteran and former factory worker who lost the use of his legs after a truck owned by the Pryor's company hit him. After writing several letters to Mike Pryor asking about work and disability compensation, none of the letters were answered, so Harold decides to kidnap Mike for a $100,000 ransom. But since Harold and Irene have never met or seen Mike Pryor they happened to abduct Kimble instead after seeing Mike's son, Glenn, give more affection to Kimble than his distant father.
