Kotoko

A young, single, mentally unbalanced mother strives to protect her infant son from a grim fate in a cruel and uncaring world, and slowly begins to come unraveled as a lonely author tries desperately to break through her icy exterior. Everywhere Kotoko (Cocco) looks, she sees double. It's gotten to the point where she can't tell what's real anymore, and upon being reported for suspected child abuse, the boy is sent to live with his aunt in the country. Meanwhile, best-selling author Tanaka (writer/director Shinya Tsukamoto) hears the lonely mother lost in song one day on the train, and grows so enamored with her voice that he proposes marriage. But Tanaka gets more than he bargained for when the deeply disturbed beauty turns viciously abusive. Later, things go from bad to worse after Kotoko regains custody of her son, and finds here already tenuous grip on reality slipping even further.
