When Chenphop’s wife, Nopnapha found out that her husband was having an affair with Mutta, she publicly humiliated her and forced her husband to stop seeing her. Then Mutta realized that her lover would not stand for her, breaking all the promises he had made to her. She fell into a deep depression and went back to her hometown where she committed suicide. On that same day her twin sister Munin came back home from the States. She blamed herself for having been one of the causes of her sister’s death and used her identical looks to exact revenge from those she perceived had wronged her sister. Thus she went to Bangkok and pretended to be Mutta.
