Triangle is a psychological horror film that unravels very slowly. A single mother played by Melissa George goes on a boating trip with her friends. What started out to be a beautiful and windy day, changes rapidly with the arrival of a storm cloud. The boat called 'Triangle' capsizes and their only hope of survival is a ship. The group of friends soon realize the ship is derelict and someone is watching them. What follows  next, is a mind-boggling affair, directed
beautifully by Christian Smith. Triangle is very hard to follow and every detail needs to be closely monitored to get the ending. 'If' you get the ending, that is!
