Liam Neeson reunites with Spanish director Jaume Collet-Serra, who helmed Unknown and Non-Stop, for this gritty action thriller about a father who resorts to brutal measures to protect a loved one from harm.

Hitman Jimmy Conlon (Neeson) is nicknamed The Gravedigger because of his prolific kill rate, some at the behest of his best friend, ruthless mob boss Shawn Maguire (Ed Harris).

For more than 30 years, Jimmy has managed to stay one step ahead of tenacious Detective Harding (Vincent D'Onofrio), but the net is slowly closing in.

Booze is Jimmy's only solace from the manifold sins of the past, but when his estranged son Mike (Joel Kinnaman) becomes a target for execution, he faces a stark choice between a crime family that doesn't tolerate mistakes and his own flesh and blood.

With just one night to protect Mike from a rival's bullet, Jimmy races to the rescue, unsure who he can trust in the unforgiving criminal underworld.
