Chan Kwai Bun has the power to see people's ''inner personalities,'' making him a very capable, if unorthodox and unstable, police detective. He is invited back to active duty by Ho Ka On, a cop investigating the disappearance of a fellow officer whose weapon has been used in multiple robberies. Ho and Ko Chi Wai, the missing cop's partner, go after an Indian suspect. Bun, however, can see both men's inner selves and suspects something else at play.
