Lately in life of ophthalmologist Catherine Бородиной oddities began: to her an impressive man came on a reception, what unoften will see in a district policlinic, and after work he met her with the bouquet of roses. On falling in love a patient resembled not very, and Катя did not understand that he needs from her. To her in general it was ill at ease since she saw falling on an asphalt Olga. A hammering together her machine hid, Катя had come running to train nurse first and at once understood: traumas are hardly consonant with life. A few days prior to death Olga left a notebook in a cabinet. Катя gathered to return him to the husband of friend, but at first decided to delete from there the photos and barged into a strange videofile: a pair goes for a drive on a lake, then a fellow suddenly begins to loosen a boat, a girl in horror is caught overside, and in a next shot she already is not present. What it after a record, who on her is taken off and what does all this relation have to Olga? Really did she become the witness of crime and forfeited for it life?
