The movie follows the premise that a regulation prevents sex for unmarried folks during the whole year except a 12h period that became a big night where people go out to accomplish all their fantasies. The story follows Ellie, who doesn't want an one night stand and has the seemingly impossible task of finding something meaningful in this night, and Owen, who was just reject by his girlfriend who wanted to "explore" someone else. They keep coincidentally meeting throughout their 12h of misadventures. Not exactly my type of movies but the jokes work well and the plot is good. There is a lot of care in the background of the scenes to add in small jokes related to the "only one night" topic. Good movie overall
