It's always a tough situation to run into an ex-lover at a wedding... The awkward conversations, the fear of sitting at the same table, the drunken flirtations that MIGHT lead to another hook-up, needless to say, it's a tightrope of emotions. Enter Sara (Allison Williams) and her ex Jackson (Alexander Dreymon), who are in the beautiful tropical islands of the Caribbean for a mutual friend's wedding and are definitely teetering on a wedding night hook-up or a drunken blow-up between each other. When after a night of partying, they need to charter a small plane the following morning to island hop to get to the actual ceremony, that is when disaster strikes. You see, the pilot on this single engine plane suffers a massive heart attack over the middle of the ocean, then these two jilted lovers are stuck trying to figure out how to fly a plane! The radio is dead, the auto-pilot isn't working, there is a dead Keith David slowly growing funky from tropical humidity, all over shark infested water, while these two try to learn how to pilot a plane through bad weather! It takes hanging out with your ex at a wedding to another level, then you add in the fear of dying in a plane crash, or even worse, surviving the plane crash and having to wait for a rescue that might not come, in shark infested waters. Keep your eye on the Horizon Line, because if you jiggle that stick a little too far, you and your ex are going to take a dangerous dip in the deep blue sea! Lucky for us though, we get a bit of Alexander Dreymon shirtless in a few scenes, which is going to turn something in your pants more horizontal to sea level!
