After the last concert by the four-man punk band The Ain’t Rights is cancelled and a replacement gig in a Mexican restaurant doesn’t earn them a penny, they get an offer to make up for it that involves playing the next day in the forests of Oregon. The show is for a bunch of neo-Nazis, but it pays well. However, once they reach the site of the irate skinheads – they sensibly open their set with a cover of Nazi Punks Fuck Off by the Dead Kennedys – everything goes wrong that could possibly go wrong. They are locked up in a room, while the leader of the gang (a terrifying Patrick Stewart) consults on how best to dispose of them. The massive slaughter that follows is portrayed by Jeremy Saulnier, who made his breakthrough in 2013 with an equally raw and violent debut Blue Ruin, with sardonic pleasure and the visible predilection for bloody genre stablemates from the 1980s.
