The Stranger (2014)

Jayne is a young and attractive widow still grieving for her husband - she's vulnerable - using pills and drink to stave off her painful loneliness. When she finds a stranger unconscious on the road in the middle of nowhere, she struggles to get him home. When he wakes he says he has no memory - he could be anyone. He may even be dangerous - and the police are looking for someone. He has mysterious glimmers of memories, and an edge of danger, which she finds herself inexorably drawn to. He makes her feel like a woman again. But Jayne needs closure - justice - for Paul Jones, the man who killed her husband, to pay for what he did. He's gotten off lightly for her husband's death, with Jayne helpless against his taunts. When Paul Jones comes to her house, drunk and violent, the stranger takes things into his own hands, changing their relationship forever...
