Life has not been kind to SAM (Simon Yam), FAI (Louis Koo) and MOK (Sun Hong Lei) as they struggle to make ends meet. Routine visits to bars seem to be their only way out of miseries.

All they have to do is sneak in and retrieve it; if they believe in his story. Sam, Fai and Mok agree to make a run for the treasure to test their fate. What they uncover is beyond anything they expected: An ancient coffin containing a ceremonial robe made of gold!
