Long Weekend (2009) English Subtitles

Peter and Carla, a couple whose marriage is faltering, decide to go on a camping weekend. When they become lost, the pair sets up camp on a remote beach that doesn't seem to be on any map. At first the trip is the romantic getaway they imagined – then slowly things begin to go wrong. After Peter disrespects the unspoiled habitat, it seems as if the surroundings are exacting revenge on the couple, as insects, animals, and then nature itself become the enemy.
