The man is asleep in his house, it's a log cabin out in the woods, a sensor goes off, waking the man from his sleep, only to look up at the device and see sensors going off all around, soldiers, he presumes are approaching. He doesn't know who sent them, but gets up regardless, he's got time, the sensors were set up out far, to give him this sort of warning.
He suits up, its time.
He cocks his gun and smiles, much like a shark, smelling blood in the water.
Gun play, gun fu, fight scenes and lots of action.
Inspired by John Wick.
