Cannon Productions' first foray into the martial arts milieu, Enter the Ninja stars Franco Nero. While visiting old pal Frank Landers (Alex Courtney) in the Philippines, master ninja Cole (Nero) is approached by villain Charles Venarius (Christopher George). Coveting Lander's plantation, Venarius tries to strong-arm Cole into turning against his friend. Our Hero refuses, whereupon Venarius brings in his own ninja Hasegawa (Sho Kosugi), the first step towards the battle-royal climax. The stunt choreography by Mike Stone is enough to make one completely forget the film's lapses in taste and logic. Enter the Ninja was followed in short order by Revenge of the Ninja.
