Elements of the typical detective story blend with comedy and melodrama in this tale of a Taipei man who longs to patch up his relationship with his estranged wife, yet finds his noble efforts sabotaged when he steps out of his car to purchase a cake, and another driver parks him in. It's Mother's Day in Taipei, and Chen Mo is eager to patch things up with his beloved wife. In order to start things off on the right foot, Chen Mo stops by the local bakery to pick up a cake. Unfortunately, that's just about the time another driver chooses to double-park in the space next to him, effectively blocking him in. The driver of the other car is nowhere to be found, and Chen Mo searches every floor of the adjacent parking building to no avail. In the course of his quest, Chen mo encounters a series of quirky characters including a one-armed barbershop owner with a fondness for fish head soup, and a mainland prostitute on the run from her pimp. In time Chen Mo finds the driver of the offending car, and invites his newfound friends along as he prepares to drive off into new horizons.
