The Grinning Man (2018)

One year ago, four people were brutally murdered near a quiet country lake. The killer was never caught, and two unfortunate punk musicians run out of gas on their way to their next gig near that same lake. The nearest gas station: one mile away. The shortest distance: a trail that cuts through the woods. All is fine until they stumble upon a mysterious jogger, who claims to have been attacked by a man with the knife, and they agree to let him walk with them. Was the jogger really attacked, or could he be the killer?
