The police have planted an undercover officer within a powerful triad gang. Simultaneously, the triad has placed a mole deep inside the police force. Both moles must race to uncover the identity of the other before their own cover is blown. The two men live double lives, each desperate to protect their secret while being eroded by the constant pressure and moral ambiguity of their roles.
