The story revolves around the complicated family line: two sisters has mutual father, but their mothers are sisters. Once their father was in love with a girl, but ended up marrying her sister. Two baby girls were born and grew up not knowing about each other.

After many years the story repeated itself again like a curse. Both sisters fell for the same man. One sister mysteriously dies under very suspicious circumstances and the official police investigation hits dead-end. The murderer is victim’s ex-lover and, what’s more interesting, husband of her sister. But to kill the innocent girl is not enough. He claims victim’s heritage, betrays his wife, swindles his business partners and imitates his own death.

Finally, police succeed in the investigation; arrest the murderer with the help of survived sister and other relatives.
