Dragged Across Concrete is writer-director S. Craig Zahler’s further exploration of the seamy underbelly of American society, particularly through the prism of how that experience causes ripple effects that throw even innocent people into the wake of the criminals.  Most of the action follows the exploits of two cops in the fictional city of Bulwark, the older burnout Brett Ridgeman (Mel Gibson) and his younger partner Anthony Lurasetti (Vince Vaughn), who get suspended from the force after they are caught on camera going a little too far in roughing up a suspect in the current environment that frowns on the perception of racial profiling. The other major story arc in the film involves Henry Johns, just released from prison, going back to a life of crime in order to provide for his mother (a drug user who has been prostituting herself for needed cash) and disabled younger brother, who has aspirations of becoming a video game developer. The two stories converge when the cops decide they’re going to snatch money from a secretive drug dealer named Vogelmann, while Henry, working for that guy, becomes the wheel-man in a bank heist.
