When a middle-aged architect (Colin Farrell) suddenly finds himself single, he’s whisked off to a special “hotel” where he’s given 45 days to find a new mate from among the other guests. The circumstances are far from ideal, mainly because the guests are largely dispassionate, mechanically going through the motions of dating, looking for anything to latch onto that might hint at potential instant compatibility. Singles who mutually possess seemingly insignificant traits, like walking with a limp (Ben Whishaw), an affinity for breakfast biscuits (Ashley Jensen), lisping (John C. Reilly) or being prone to spontaneous nosebleeds (Jessica Barden), gleefully view these mundane attributes as possible foundations for romantic kismet.
