A single mother clings to life amid nightmarish mental problems and self-mutilation. Japanese folk rock artist Cocco delivers an astonishing performance as Kotoko, a woman for whom the thin line between good and evil is something she traverses every day in the most shocking ways. Darkly humorous, horrific, compelling and disturbing, this is one film you won’t forget in a hurry. For more Tsukamoto, see Tetsuo: The Iron Man and Tetsuo II: Body Hammer.
