Convicts Tony Curtis and Sidney Poitier escape from a chain gang. Curtis' character, John 'Joker' Jackson, hates blacks, while Poitier's character, Noah Cullen, hates whites. However, the men are manacled together, forced to rely on each other to survive. Captured at one point by a lynch-happy mob, the convicts are rescued by Big Sam Lon Chaney Jr., himself a former convict. The men are later sheltered by a lonely, love-hungry widow played by Cara Williams, who offers to turn in Cullen if Joker will stay with her. By the time the two men are within hailing distance of a train that might take them to freedom, they have become friends. The script for The Defiant Ones is credited to Harold Jacob Smith and Nathan E. Douglas. The latter was really Nedrick Young, a blacklisted writer, whom producer Stanley Kramer hired knowing full well that Young was using an alias when 'Douglas'' credit appears onscreen, it is superimposed over a close-up of a truck driver -- played by Nedrick Young.
