THE BEAST OF THE YELLOW NIGHT

The film is set near the end of World War II in the Philippines. Satan (Vic Diaz) saves murderer Joseph Langdon (John Ashley) from death on condition that he become his disciple. Satan has Langdon inhabit the bodies of several people over the years, bringing out the latent evil of those around them and carrying out the devil's evil deeds for the next 25 years. Inhabiting the body of Phillip Rogers and with his face, Langdon tries to exert his own free will, but becomes a hairy, murderous beast — a werewolf on the rampage — and kills several people. His wife Julia (Mary Wilcox) tries to support and comfort him during the day, as does his brother Earl (Ken Metcalfe), but when he meets blind former bandit Sabasas Nan (Andres Centenera), he starts to find the strength to fight back. Inspector de Santos (Leopoldo Salcedo) recognizes Rogers as being Langdon and takes him into custody, putting him under house arrest. Rogers attempts to make love to his wife, but changes again and escapes. When he and Nan try to leave the city, they encounter the police and military, and Rogers changes again, battling against the combined forces. When a gravely wounded Sabasas Nan asks Rogers to pray for him, he does so, and at that moment, he is shot by Lt. Campos, dies, and reverts to his true age, his soul now free.

Langdon is fatally shot after praying for a dying companion, reverts to his true age, and is freed from Satan’s control.

The film resolves its central conflict by linking Langdon’s redemption to an act of compassion and spiritual release. By praying for Sabasas Nan, Langdon asserts his humanity and breaks free from Satan’s pact, symbolized by his physical transformation back to his original self at death. The ending underscores themes of free will, redemption, and the possibility of salvation even for the damned.
