Shock Wave

Cheung J.S. (Andy Lau) is a bomb disposal officer in Hong Kong, the kind of man who walks toward the device while everyone else walks away. Herman Yau sets him against Blast (Jiang Wu), an explosives specialist who has taken hold of an underground tunnel and says the hostages die if his demands go unmet. Every minute in the tunnel puts more lives on the line, and the clock keeps running.
