Cole, an ex-soldier having completed his ninjutsu training in Japan, visits his war buddy Frank in the Philippines. Frank owns a large agricultural estate but is being harassed by the powerful and unscrupulous businessman Charles Venarius, who wants to seize the land to exploit its natural resources. Cole's arrival quickly escalates the conflict as he uses his ninja skills to protect Frank and his wife Mary-Ann from Venarius’s relentless attempts to take over the property. Venarius, realizing Cole's prowess, decides to bring in expert help to eliminate him.

As the situation intensifies, Venarius hires Hasegawa, an old nemesis and equally skilled ninja, to get rid of Cole. The tension between Cole and Hasegawa becomes a personal duel against the backdrop of Venarius’s ruthless business tactics. Meanwhile, Frank faces increasing psychological strain due to the constant pressure and rising danger to those around him. The early part of the film explores Cole's adaptation to civilian life, his loyalty to friends, and the moral dilemmas he faces as he combats corruption and defends the land from falling into malicious hands.
