Kung Kasalanan Man (English: If It's A Sin[1]) is a 1989 Philippine thriller melodrama film directed by Eddie Garcia from a screenplay by Amado Lacuesta Jr. and Raquel Villavicencio, based on a komiks serial of the same name written by Gilda Olvidado.
However, after experiencing a near-death experience with the unidentified men who fired gunshots at the front of their house, she decides that she and Yvette will go to the United States.
While Irma and her daughter go to America and Raullo is on a business trip in Australia, she assigns Jo, her longtime friend since high school, as a house sitter.
While doing so, Jo began stealing things owned by Irma inside the house, including jewelry, fancy clothes, and her safebox.
With the jewelry and safebox, which contained her photos and bank accounts, that Jo stole, she succeeded in stealing Irma's identity through plastic surgery.
When Jo, now the fake Irma, returns to the mansion, many people including Aling Miding thought that their employer would stay for a long time in America.
The following day, Raullo returned home from his business trip, only to be refused to let him in by the new house helpers and met his demise when unknown assailants shot him to death.
