In Knuckledragger, hooligan and low-level criminal enforcer Jason “Candy” Stahl (“Irish” to his sometime girlfriend Rosario) has made a good life collecting money for his boss Otis, breaking the occasional leg or elbow, fucking Rosario, and living the life in Revere, MA. One collection trip, though, at the Diovisalvo Liquor Store, unravels events that turn Candy’s life into a horror-show.
In quick succession he moves up a notch in the organization, overseeing a chop shop, while he falls in lust with Otis’s girlfriend Nina, gets beaten for insubordination, and is forced to run when Otis finds out about Candy and Nina’s affair.
Events stretch as far as Houston, Texas, where Otis and Candy have a final showdown where everything is at stake. Loser gets nothing.
