Kevin (Andrew Lin), a terrorist, blows up a plane somewhere over Singapore. In Hong Kong, two impoverished computer geeks, Peter (pop star Aaron Kwok) and Benny (Daniel Wu), meet up with Peter's brother, Greg (Ray Lui), who is on the run from Singapore after being named as a suspect in the bombing. Gun play, location shifts, and an alliance with the mysterious Salina (Singapore TV star Phyllis Quek) ensue as the techies go in pursuit of justice and international terrorists. ~ Rebecca Flint Marx, Rovi
