Angolan Bush War veteran Cole (Franco Nero, Django) is a westerner living in Japan who has been inducted into the secret fighting rituals of Ninjitsu - the darkest and deadliest of all martial arts. Coming to the aid of a war buddy in the Philippines, Cole is dragged into a land dispute with a scheming oil baron. With his henchmen no match for the imposing Cole, Venarius hires the best assassin money can buy - Ninja Hasegawa (martial arts super star Sho Kosugi) enters the fray with a lethal agenda. Martial arts legend Sho Kosugi (Prey For Death) steps into the fray wielding swords and shuriken - displaying super-human abilities of strength, speed and lethal Ninja know-how in the 1980s action classic Return of the Ninja. When a ruthless band of Ninja assassins slaughters the family of Cho Osaki (Kosugi) in his homeland of Japan, he flees to America in the hope of building a new life. A former Ninja himself, Osaki tries to escape his violent past but soon discovers he has become the pawn of a ruthless drug trafficker.
