Ne le Dis à Personne 2006 / Now On Kanopy

Francois Cluzet, who you may remember from The Intouchable, plays a man whose wife is killed and is accused of murdering her. To make matters even more confusing, signs that his wife is actually still alive surface. This well thought out thriller is at all times the furthest thing from boring and has, among other great components, well crafted chase scenes as the protagonist looks for 8 years of unanswered questions.
