It's been 10 years since Harry Burns (Billy Crystal) and Sally Albright (Meg Ryan) shared that dreadful car ride from Chicago to New York bickering about whether platonic friendships between men and women really do exist. When they run into each other all those years later, the debate still stands, and so do their opinions. As the two begin to spend more quality time together, they reevaluate their own friendship. Can they keep things platonic without sex getting in the way? Spoiler alert: they can't, and what follows is one of the most memorable New Year's Eve kisses in all of romance history!
