Into the Perilous Night: PTU

As a member of the Police Tactical Unit (PTU), Sergeant Lo (Lam Suet) cruises on his own, beating and brutalizing punk kids who report directly to a group of gangland thugs. Lo's major problem is that he's lost his police-issue handgun. He follows all leads trying to track it down, even if it means betraying his fellow officers and making a deal with the thugs. A brutal action film, PTU is leavened with moments of absurd humor.
