Roller Blade Killer.

When he’s not tending bar and performing lead in a choreographed rollerblade floorshow at the local hotspot, disdainfully flipping off his mother’s latest lay, or sleeping with the girlfriend of his wealthy, four-wheeled rival, rollerboy Cheng Tung-chuen is tearing up the Taipei streets with his rollerpals, which is how he witnesses hitman Billy Chow kill three other hitmen and light the bodies on fire, but since he has no father figure in his life, he ends up spending the night at Billy’s because Billy feels really bad about his career and just wants to fall in love with supercop Yvonne Yung Hung.
