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. But that's what One Night Only is.
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. During this one night, singles are free to have sex without the threat of legal crackdown; the rest of the time, they are monitored via implants that detect body chemistry and alert the police if shagging is detected. Basically, it's The Purge: but for Sex.
