Okay, here is a plot summary for the movie "Fatal Weekend" (assuming you mean the 2017 Australian film):
Plot Summary:
"Fatal Weekend" centers around a group of young friends – Chloe, Gemma, and their respective partners, Ben and David – who decide to spend a weekend together at a remote and seemingly idyllic beach house on a small, isolated island off the coast of Australia.
Initially, the atmosphere is relaxed and carefree, typical of a summer getaway. However, the serene vibe quickly deteriorates as unexplained and increasingly terrifying events begin to unfold around the house. Mysterious occurrences, potential intrusions, and paranoia start to grip the group.
As the weekend progresses, the friends find themselves isolated not only by the surrounding ocean but also by a sense of encroaching danger. Trust breaks down, old secrets and resentments surface, and the lines between reality and fear become blurred. They are forced to question who might be responsible for the threats they face – is it an external attacker, or could one of their own be involved?
The group must fight for survival against the escalating horrors that stalk them within the confines of the house, questioning each other's motives and confronting the potential darkness hidden within their own group dynamics. The remote location and the escalating terror create a tense and claustrophobic atmosphere, leading to a shocking and brutal conclusion as the "perfect weekend" turns tragically sour.
