Shinya Tsukamoto, the cult director of the cyberpunk Tetsuo series, presents an unnerving film about mental instability. Kotoko (folk-singer Cocco), a young single mother, lives alone with her baby son. Suffering from an unknown illness that makes her see double – especially people – and not knowing which version of the person is real, it severely impacts her day-to-day life, often leading to her to lash out violently.
As her situation worsens and she becomes a liability, her son is taken from her a put in the care of her sister. Kotoko is left alone with her own thoughts – and for a person with an already broken mind that is a very scary place indeed.
