　　結(jié)識小明（楊靜怡）前，小四（張震）是典型的乖仔，是父母的希望和兄妹的驕傲（一家人指望他考上名牌大學(xué)將來提升全家的社會地位），他有一個喜歡搖滾樂的自稱“小貓王（王啟贊）”的好友，兩人雖會去樹林看人幽會，但過的是與周圍諸多在“小公園”混的少年人完全兩樣的生活。　　喜歡上小明后 ，小四便像跌進一個無底深淵，開始被外界的各種力量牽著鼻子走。新識仰慕對象honey（林鴻銘）意外身亡，一向敬重的父親的自尊與精神因為某次事件嚴重受損，加上將一次次“欺騙玩弄”他感情的小明“看透”，血氣方剛又有很強道德感的小四終于走上犯罪的道路，期望用自己的刀結(jié)束事件的根源。但小四不知的是，他眼中的根源只是這條食物鏈中微不足道的一環(huán)。

　　The main character is Dr. Max Holst, a successful neurosurgeon. One day an intense little man named Steinmetz shows up, who has the real ability to create objects out of thin air, using only his mind. As no one believes him at first, he is held at a ward for mental patients, but manifests the key to his door and escapes. As he has a special interest in Dr. Holst, Steinmetz subsequently invites Holst to his large mansion, which is full of expensive paintings and sculptures, and proves to him that he can in fact materialise objects. Steinmetz’s abilities are evolving by leaps and bounds, and is progressing from being able to create objects only to being able to create living things. His ultimate ambition is to be able to create a human being. He tells Dr. Holst that if he will only perform a certain brain operation on him, Steinmetz will become able to attain his goal. He’s got all the necessary equipment set up in his basement. Dr. Holst, however, is too spooked by the whole thing to agree to this mad scheme, and refuses. Steinmetz then sets about manipulating Holst’s life, to pressure him into performing the operation. By then Steinmetz has become able to create a temporary human being, and in the hope that he can perhaps make his own creation perform the operation, he manifests a doppelganger of Dr. Holst. This double proceeds to take over Dr. Holst’s life, creating chaos for him professionally and personally. And then Dr. Holst starts fighting back. The ending has the dual virtue of being both unexpected and satisfying.
