It's not often that one finds a movie about federal regulation, much less a high-concept rom-com set in a quasi-dystopian alternate present that no one quite realizes is dystopian. The movie is set in present-day New York, three years after the passage of a federal regulation, simply known as "the mandate," that banned all sex outside of marriage—except for, you guessed it, one night only. One Night Only posits that where sex is concerned, the public might do the same. Since marital sex is legal in the movie's rom-com dystopia, why aren't people getting sham married for a night or two, or while they shack up? It's a question worth pondering for more than one night.
