Yolly (Nora Aunor), a flower vendor and her brother Efren (Dan Alvaro), who works as a driver and hired hit man for ruthless money laundering lady Connie (Gloria Romero), live a hardscrabble and bleak existence in the underbelly of the tourist/fashion district of Manila. Escaping from a violent past from the provinces, the siblings world collide with Connie's gang when Yolly witnesses a rape and murder perpetrated by Connie's son (Toby Alejar) and Efren decides to double cross Connie for her money. A nightmarish resolution between hunter and hunted on an empty cargo ship anchored in Manila Bay and final confrontation between Yolly and Connie over the missing half million dollars makes for a gripping film-noir drama.
