Standoff (2015)

Starring Laurence Fishburne and Thomas Jane. Combat veteran Carter Greene (Jane) lives alone in a rustic farmhouse where he grieves the death of his young son and the resulting failure of his marriage. Meanwhile, Bird is an orphan who's experienced too much loss for somebody so young.
As Bird mourns her parents on the anniversary of their death, she watches professional assassin Sade (Fishburne) storm the graveyard and kill a group of funeral goers. Terrified, Bird springs into the woods, followed closely by the sadistic assassin. She eventually takes shelter in Carter's farmhouse, where Carter vows to protect her and avenge the murder of her family.
