Temnye labirinty proshlogo (2013)

After a quarrel with her husband, Lisa leaves home. The next day she is found by her brother-in-law lying unconscious in the forest. When she comes round, it is clear that Lisa has lost her memory and will therefore have to try and resume her old way of life, but Boris, her husband seems strange and alien to her, and she cannot adapt to her daily routine. Her mind begins to be tortured by dim recollections interspersed with complete memory lapses. Lisa begins to fear she is losing her mind. In the meantime Irina, a young receptionist at the local private hospital is attacked by an unknown assailant, but a casual passerby intervenes and saves her. Could there be a link between Lisa's memory lapses and the attempt on Irina's life? There is, but the link is totally unexpected.
