A former hit-man for a drug cartel becomes a vigilante to pay for his sins and find redemption.

A supernatural thriller, laced by flashbacks, and set in Canada’s North-West, “The Stranger” turns on the mysterious titular figure of Martin, who comes to a small quiet town seeking to kill his wife Ana who suffers from a very dangerous decease that makes her addicted to human blood - just like himself-. However, when he arrives to the town, he discovers that Ana has been dead for a couple of years and decides to commit suicide to definitely eradicate this dangerous decease, but, before he can do it, Martin's brutally attacked by three local thugs led by Caleb, the son of a corrupt police lieutenant, and the incident suddenly starts a snowball that will plunge the community into a bloodbath.

A powerful Argentine gangster uses everything in his power to stop the woman that wants to kill him, a sexy mercenary known as "the machine gun woman". The staggering sum of cash he offers for her head sets in motion an army of hitmen. And also, by accident, bursts in the life of naïve DJ Santiago, a common youth that will have to steel his guts against the underworld, and above all, survive the irresistible - and bloodthirsty - Machine Gun Woman.
