Lena drove home during lunch break and found a textbook picture: her husband in the bedroom with his best friend. At that moment, Lena realized: she and Sergei had long become strangers and this was an excellent reason to put an end to their unhappy marriage... But suddenly thoughts about a failed personal life were crowded out by other events - a guy in expensive clothes whom she and her friend Rowena picked up on the city beach. The stranger was clearly in trouble and didn’t remember anything about himself... His identity was quickly established, but the question of who kidnapped him and why his memory was erased remained open.

The friends did not yet know what they would have to endure due to the fault of the strange guy they found on the beach...
