Who's Quentin (2005)

In the service of underground crime lord "Felix" Martin, Kevin and "Knaschti" get assigned to an apparently simple task: Stealing a bag from a rivaling gang. But then Martin kills himself and the bag is lost. The two remaining friends are granted a deadline till dawn to get it back... Chased by Felix's eccentric handymen as well as the gothic "Band of Doom", the two small time crooks end up in the crossfire of two hostile gangs, whose notorious members, philosophizing sadists and comic-style dandies will have stand nothing between themselves and the enigmatic bag. At dawn all hell (metaphorical as well as literal) breaks loose and one question still has to be answered: Who's Quentin?
