Billed as the first East meets West Western, and directed by Terence Young, RED SUN is based on a true story from the American Wild West of 1870, when paths cross for an outlaw (Charles Bronson, The Dirty Dozen), a gunfighter (Alain Delon, Le Samourai), a prostitute (Ursula Andress, Dr No) and a Samurai warrior (Toshiro Mifune, Rashomon).

Bronson plays Link, a train robber forced by the Japanese Ambassador to help regain a priceless sword stolen by Link’s double crossing partner Gauche (Delon). Accompanied by Kuroda (Mifune), the Ambassador’s bodyguard, he travels the West in pursuit, along the way stopping in a brothel to pick up Gauche’s girlfriend (Andress) as hostage. Kuroda plans to kill Gauche straight away with the sword itself, to redeem his honour, but Link needs him alive to find the loot from their last robbery. Joined uneasily together with a common goal they have only seven days to find Gauche or Kuroda must die by his own sword.
