Twin sisters, similar in appearance differing in disposition, go about life in different ways. Duen, a capricious model and actress, is inconsiderate of anybody else’s interests or feelings. Pit has taken care of Duen since the death of their parents and is still looking out for her. While Duen was in a scandalous relationship with a rock musician, Pit had met Warit, a worthy young man. At first, he confused the twins but soon recognized their differences. By strange coincidence, Warit turns out to be the nephew of Duen’s new lover. Duen suddenly tires of the elderly uncle, switching her attention to the nephew. The more Warit resists Duen’s advances, the nastier her tricks become to ensure Pit and Warit quarrel.
