Chino, a wealthy playboy, meets Lani, a GI baby of a former prostitute, during a bar-hopping spree in Angeles City. During their whirlwind romance, a clash with a mayor's son leads his brother, Sammy, to send him to America. Lani, unaware of Chino's departure, follows him to Manila to tell him she is pregnant. When Sammy refuses Lani entry to the house, his driver, not looking at the commotion outside his car, is told to ignore Lani's pleas, and the driver accidentally bumps into Lani, causing a miscarriage.
With little else going on for her, Lani clings to the American dream. Blessed with beauty and a whistle-bait figure, she plans to use these assets to inch her way toward advancing her social status, and subsequently, to plot vengeance against the brothers. She wins Ms Body Beautiful and works as a joiner in a Manila bar, all the while monitoring the status of Chino and Sammy. Lani's plot begins to unravel when the American Ambassador takes her to a society ball. As part of the elite, Sammy also attends the ball, and the moment he lays eyes on Lani, he is smitten.
Meanwhile, a homesick Chino in America finds comfort in a new friend, Gwen, who becomes a confidante. Gwen quickly captures his attention, and he falls for her. One night, Chino receives a phone call from Sammy asking him to come back to Manila to meet his new sister-in-law. Chino, together with Gwen, heads back to Manila to be introduced to the bride. Chino's excitement turns to despair when he realizes that his new sister-in-law is Lani, the girl he abandoned.
Unable to confess to Sammy and Gwen, Chino's paranoia and Lani's seductive maneuvers create a growing rift between the brothers. Unbeknownst to them, the plot has been carefully planned by Lani and Gwen. Gwen is actually Lani's long-lost sister who was adopted by a Filipino family in America. Gwen, trying to mend the past, agrees to Lani's plan, but the arrangement becomes more complicated as Gwen slowly falls for Chino.
Lani feels betrayed by Gwen's feelings for Chino, and resolves to win him back. Sammy discovers the infidelity of his wife and his jealousy erupts into rage. He soon discovers the connivance of the sisters and takes Lani to a remote cabin to kill her.
Gwen learns from their mother about Lani's miscarriage and decides to tell Chino about Lani's misfortune together with her secret as Lani's long-lost sister. Realizing the absence of Sammy and Lani in the house, Chino and Gwen seek help from Sammy's ex-wife. After they obtain vital information about the whereabouts of Sammy and Lani, Chino and Gwen head to the cabin to save Lani. They find the cabin as Sammy is torturing Lani. Chino and Sammy wrestle for the gun, and the unthinkable happens: Chino kills Sammy.
Chino faces trial and is found innocent. As he comes out of prison, Gwen waits for him. While Chino and Gwen start their new lives, Lani, who now inherits Sammy's fortune, finally fulfills her American dream.
