Source-derived summary

Nightmare Detective (悪夢探偵, Akumu Tantei) is a 2006 Japanese horror film directed by Shinya Tsukamoto and released by Movie-Eye Entertainment Inc, starring Ryuhei Matsuda and Hitomi. Masanobu Andō and Ren Osugi play supporting roles, and Tsukamoto himself plays the unnamed villain. The film is shot entirely within Adachi, Tokyo.

Nightmare Detective 2 was released in 2008. Matsuda returns in the lead role of Kagenuma. Hitomi declined to reprise her role.

Plot

The film opens with a middle-aged man drinking beer, when a young man Kyoichi Kagenuma (Ryuhei Matsuda) appears from under the floor, and it is revealed that the older man, Mitake, is a former teacher of Kagenuma's father. Kagenuma is being haunted by the soul of a daughter whom his wife had aborted without his knowledge. Mitake refuses to help him.

Kagenuma wakes up in hospital next to the body of Mitake, and surrounded by Mitake's children.
