Olha and Vira are twin sisters. 12 years ago Olha stole Vira's fiancé, Ihor, married him, started a business and became rich. Vira is still single and works as a waitress at a provincial restaurant. 12 years later Ihor finds Vira and tells her there was an attempt on Olha and now she is unconscious at hospital under a fake name, to protect her identity. Ihor begs Vira to temporarily pretend she is Olha to sign a very important contract on her behalf. Finally Vira agrees to become Olha for a couple of days, but she does not understand it makes her a pawn in a big game in which both sisters' lives are at stake.
