The 2009 film 'Triangle' follows Jess, a single mother, who goes on a boating trip with friends, only to get caught in a mysterious storm. They find a deserted yacht, but soon start to experience a series of chilling, inexplicable events that make them question their sanity.
A capsized yacht trip leads aboard a derelict liner where the rules of the film start folding back on themselves. The second viewing reveals that what looked like a horror movie is actually a closed-loop tragedy about a mother trying to undo a single moment.
The protagonist is trapped in a time loop, causing deaths.
