Three apparently unrelated suicides occur on the same day in Tokyo. One involves a young athlete, one a groom at his wedding reception, and the third an elderly man celebrating his wife's birthday. A middle aged detective investigating one of the cases begins to suspect a connection between the three when he discovers that each person mentioned a "green monkey" before they died. With the help of a young psychiatrist he formulates the theory that hypnosis is somehow involved. In the mean time other bizarre "suicides" are reported and the mystery intensifies. Who will be next? What is the truth? Can more deaths be prevented?
《催眠》：一本出色的心理小说和一部俗滥的恐怖片。你催眠自己，葬送了我的终身相守。。七年前写的影评，献给《催眠》。《催眠》：每个人心里都有一只绿猴子。精彩的心理惊怵片。最喜欢的日本电影《催眠》 顺带提提其它。很失望。《催眠术》。少女时代看的最后一部恐怖片。不要宿命。
