What is One Night Only about?
One Night Only takes place on “the least romantic night of the year,” the only night when singles are legally allowed to have sex. Universal teases, “Recently dumped Owen and hopeful romantic Allie might be the only two singles in the city looking for more than just a quick encounter. They both feel a spark when they meet, but a series of missteps and side quests complicate their night, keeping them apart. As they each race toward and away from each other across the city, they just might discover that the one thing they want most is closer than they think.”

So, what is this movie actually about? From the trailer, we can tell that Owen and Allie have an instant connection, culminating in her arriving at his pizza place late at night. As the clock rewinds 10 hours, the duo is shown separately, begrudging the sexy quasi-holiday, surrounded by singles getting it on all across the city. When the two bump into each other, they question, “What about us?” before proceeding to share some A+ banter. Did we mention their sexual chemistry is off the charts?
