Nerve

A man Jakob Evans played by Christian Clark is determined to find closure after he discovers his wife, who is tragically killed in a car accident had been having an affair. First time feature director, Sebastien Guy cleverly guides the audience through Jakob's tangled journey as he becomes more and more obsessed about his former wife's mystery lover and embarks on a mission to discover this man's identity and track him down. Unable to live surrounded by reminders of his wife in the home they shared, Jakob rents a room in a seedy share house with a disturbed junkie-ish girl Grace (Georgina Haig) whom he befriends and enlists to help him. The pieces of the puzzle come together bit by bit throughout the film, resulting in a fascinating twist at the end. It can be likened to Christopher Nolan's Momento both in mood and narrative, and like Momento, there are a lot of questions and answers which aren't served on a platter which only adds to the intrigue.
