Four Glasgow losers sentenced to community service are introduced to the world of whiskey tasting by their crew supervisor, and the most intelligent and intrepid of them, an expectant father trying to escape the working-class cycle of poverty and violence, hatches a scheme to steal some rare scotch from a distillery before it’s auctioned for a million pounds or more. Proletarian filmmaker Ken Loach has tried his hand at comedy before (Looking for Eric), with less than stellar results, but this time he and his longtime screenwriter, Paul Laverty, find a good balance between drama and wacky character moments; the heist comedy is nicely underplayed, though thematically it’s fairly consistent with Loach’s other work, suggesting that the only way to triumph over the thieving rich is to beat them at their own game.
