Set in the City of Angels on New Year's Eve, one miserable man pledges to spend his New Year's Eve alone, moping in his bed in the dark while the world around him is celebrating the start of a new year. That plan lasts all of two seconds when his buddy persuades him to leave a personal ad for a midnight companion on Craigslist. This leads him to recently single Vivian, whose New Year's Eve plans involve kissing anyone but her ex-boyfriend at the stroke of midnight. Despite being total strangers, the two spend the day gallivanting all over the city together. By the time midnight rolls around, it's as if they've know each other all along.
