Enter the Ninja

Cole, played by Franco Nero, is a martial artist who completes his ninjutsu training in Japan and visits his war buddy Frank Landers and his wife Mary Ann in the Philippines. They are being harassed by Charles Venarius, a wealthy businessman, to sell their property due to an oil deposit beneath it. Cole thwarts the henchmen and later infiltrates Venarius' base with Frank, leading to a confrontation with Hasegawa, a rival ninja from Cole's old training days.
