After one of their group is caught for speeding a group of trouble-making teenagers decide to prank the local police officer. It starts with simple speeding pranks but gradually moves to more elaborate and bizarre pranks.

Tarō is a vagabond, a wannabe, an urchin, and not what anyone would call mainstream. He does not care. Do not even ask him about his background or age. He would not know and he would not bother. The man meets two others and he begins to experience a new set of conditions.

Four strangers (a verbose romantic, a human lie detector, an expert pickpocket, and a woman with a preternaturally precise sense of time) are brought together by chance when they inadvertently team up to thwart a bank robbery. Recognizing the potential of their combined talents, they decide to form a bank-robbing gang themselves, just for the fun and romance of it. Their heists are played out swiftly and coolly, less like robberies than performance art. Eventually, the foursome's good-natured crime streak is interrupted when a man from one of their pasts creates a whirlwind of extortion and double crossing.
