In this case, he will return Olga alive and unharmed. Despite the fact that the allotted time is running out, Maksim is in no hurry to save his wife; first he needs to solve all his affairs, hide the evidence, deal with his pregnant mistress and fraudulently re-register Olga's business as his own. Olga witnessed a conversation incriminating Maksim; she is disappointed and does not recognize her husband. Fearing for his safety, Maksim is ready to do anything, including even killing his own wife.
