In a movie that's exactly what it sounds like, Jamie (Mila Kunis) and Dylan (Justin Timberlake) decide to dabble in a sexual relationship with no strings attached. (But don't confuse this with the movie quite literally called "No Strings Attached," which is the same concept with different actors.) For a while, the two have a lot of fun, having casual sex while avoiding anything serious. After all, the friends-with-benefits relationship starts in the first place because they're tired of commitment. So what happens between the two, do you ask? We'll give you three guesses, but you'll probably only need one.
