By now, I’m sure you know the drill.
Kersey’s back in New York, but now he’s in witness protection for some reason. His new girlfriend’s a fashion designer, who’s ex is a mobster using her business for a wee bit of financial laundering.
The girlfriend is killed, the ex grabs his daughter and treats her like a hostage, Kersey kills a bunch of people. The end.
There are a couple of neat kills, particularly the one with the football, and it’s better than DW4, but there was really nothing left to be said by this point.
