Two 17-year-old Moscowite girls, Olya and Sasha, are going to the Crimea to meet Olya’s father Sergey. Sergey has lived in a small seaside village his whole life and he has never seen his only daughter. When Olya finds herself at the threshold of her father’s house, she gets scared of meeting him. Olya asks Sasha “to tradeplaces with her”. So Sasha introduces herself as Olya and pretends to be Sergey’s daughter while Olya claims to be her best friend. At first girls have their fun. Little did they know that this innocent joke will turn into great drama and change their lives forever.
