One day, two teenage sisters, Sunny and Heather, did not return home. Disappeared without a trace. For many years the police searched for them unsuccessfully, and even the girls’ parents had given up hope of seeing their daughters again... And now, thirty years later, a woman came to the police and made a sensational confession: she is Heather, one of the sisters who disappeared many years ago. Her mother urgently arrived at the station for identification. And then things got weird. The arrested woman spoke about such details of the childhood of two sisters, which, it seemed, she should have forgotten long ago, but she did not remember the really important things at all... Was it Heather? And if not, then who is she and why is she impersonating her?..
