What if your actions from yesterday haunt you to today? It's been 10 years since two school buses crashed into a canyon in Tennessee. Only nine young people were able to save themselves. When one of them takes her own life a little later, the others make a pact: they want to meet every year to commemorate that terrible night. To protect each other. To keep each other in check. Now, on the tenth anniversary, the shock: Another survivor is dead - his body was found in the very beach house in the Outer Banks that has become their refuge during their meetings. The support in the group is crumbling. Then an approaching storm threatens to cut off the house from the outside world. Can they still trust that they will protect each other?
