Movies like The Fall of the American Empire

A shy, insecure delivery truck driver accidentally arrives on the scene of a major crime and happens to pick up two bags of cash and hide them in his truck. As if interrogation by two tough police detectives isn't enough, the guy, who has a doctor's degree in philosophy which makes his mind mingle with remorse, must get rid of this dirty money. Only the help of a prostitute and a former biker released from jail might get him out of trouble, especially when a gang leader is very eager to get his cash back, or kill whoever is responsible for this mess. However, even the two bumbling detectives are monitoring the case as well.
