腿有残障的科学家黄三太(江口洋介)率领科学小组(大S、陈柏霖等)发明“孟结海绵”,捕获囚禁了一个十三岁男孩的鬼魂,为了查出该男孩的死因,以便自己死后也能变成类似的鬼,黄三太找来有超常能力的探员叶起东(张震),令其跟踪被放出去的男孩。最终,叶起东发现男孩是被他的亲生母亲杀害。 其后,叶起东从男孩的双眼间看到一条细丝,它似乎连接着某种神秘的力量。科学小组成员因为害怕男孩伤害他们,再次将他隔绝拘禁,不想因此扰动了细丝的另一端,更为恐怖凶残的力量被释放出,小组人员先后一一离奇死亡,叶起东与女友(林嘉欣)也受到该力量的追踪。In Taipei, the crippled scientist Hashimoto uses his invention of "Menger Sponge" to capture the energy of the spirit of a child in an old building. He invites the specialist in reading lips, Detective Tung, to join his research team that is studying the phenomenon to understand the movements of the lips of the ghost. Hashimoto is trying to disclose why the energy of the ghost does not dissipate, and Tung discovers the identity and the dramatic story of the boy. He was sick with tumors and was killed by his own mother and buried nearby a nuclear plant. Hashimoto deduces that the rage of the boy for his mother associated to the location where the body was buried were the reason to keep the energy. When the government decides to shutdown the research, Hashimoto becomes insane and takes the spirit with him.
