The story follows the intricate events that ensue after a young driver named Zhang Xiao steals a bag of 1 million yuan belonging to mob boss Uncle Liu (whom we first meet gleefully torturing one of his childhood friends). Soon enough, there's a hitman after the money -- not to mention an assorted cast of on-the-make individuals, each with their own intentions and desires.
Zhang is planning to use the money to take his girlfriend to South Korea, so that a failed plastic surgery operation can be corrected. Most crime thrillers are about freedom, escape, morality -- there's always someone looking to break free of the system. But here, everybody's already been corrupted by society, by its financial and cultural demands. Those cellphones constantly lighting up in the characters' pockets are the central accessory of modern capitalism. Everybody's always reachable, connected, compromised.
The surprisingly vibrant, hand-drawn images of Have a Nice Day revitalize the story's more tired elements. It may not give us anything new, but Jian Liu's film looks lovely and, at 77 minutes, doesn't overstay its welcome.
