The movie watches the narrative of a family whose tranquil occasion takes an unforeseen turn when four veiled “outsiders” land at their shoreline home. Wanting unwinding and detachment, Adelaide Wilson comes back to her youth home with her better half Gabe and their two youngsters for an ideal summer escape. Frequented by an unexplained and uncertain injury from quite a while ago, and irritated by a progression of abnormal occurrences, Adelaide feels that her distrustfulness ascends to disturbing chances as it turns out to be increasingly more sure that something awful will influence her family. In the wake of spending a decent day at the shoreline with their companions, Adelaide comes back with her family to their vacation home. Be that as it may, as the night advances, their serenity transforms into pressure and turmoil when four baffling outsiders arrive excluded.
