Triangle

Triangle is a 2009 psychological horror film written and directed by Christopher Smith and starring Melissa George and Michael Dorman. The film was released in the United Kingdom on 16 October 2009. George portrays a single mother who goes on a boating trip with several friends. When they are forced to abandon their ship, they board a derelict ocean liner, where they become convinced that someone is stalking them. Plot Jess prepares to take Tommy, her autistic son, on a boat trip with her friend Greg and hears the doorbell ring, but no one is there. Jess drives to a Florida harbor without Tommy, explaining that he is at his special needs school, and boards Greg's boat with his deckhand Victor, his married friends Sally and Downey, and Sally's friend Heather. At sea, a storm approaches, and while Greg radios the Coast Guard, he picks up a distress signal from a woman frantically pleading help. The woman says that someone is killing everyone but is cut off before she can provide her location. The storm capsizes the boat and Heather is swept away by the ocean. The others climb onto the overturned boat when the storm clears. The survivors board an ocean liner as it passes. It appears to be deserted despite the fact that they saw the silhouette of a person on the bridge deliberately ignoring their cries for help, and there is fresh food in the dining room. Jess experiences a sense of déjà vu as they explore the ship. They find Jess's keys near a display case for Aeolus, the ship's namesake. Jess spots someone watching them and Victor gives chase. She and Greg find "Go To Theater" written in blood on a mirror, but Greg insists it's just the crew playing a prank. Jess returns to the dining room, where the food is now rotting. Victor, covered in blood, tries to kill Jess but she fights him off. She hears gunfire and follows it to a theater, where Greg lies dead of a gunshot. Sally and Downey say that Greg told them Jess shot him. A masked shooter kills them and chases Jess; she disarms the shooter, who tells her "You have to kill them; it's the only way to get home" before falling overboard.
