A new trailer depicts a normal meet-cute before setting it on the one night a year when single people can legally have sex

For the most part, the trailer for the upcoming film One Night Only looks like the sweetest possible version of a romcom. A handsome, sensitive-looking man (played by Callum Turner) flirts relentlessly with a big-eyed oddball in a sexy dress (played by Monica Barbaro). They bump into each other, nudge each other, roll their eyes at each other. As a YouTube comment underneath the trailer (that has been liked more than 3,000 times) says: “Romantic comedies are back.”

However, tucked away in this adorable little trailer is a premise that might just be the most confusing in living memory. As Turner’s character walks lovelorn through the streets of New York City, his voiceover says: “Finding love is hard enough. Try doing it on the one night of the year single people are legally allowed to have sex.”
