An aging ex-boxer gangster (Liam Neeson) working as muscle for a Boston crime boss (Ron Perlman) receives an upsetting diagnosis. Despite a faltering memory, he attempts to rectify the sins of his past and reconnect with his estranged children. He is determined to leave a positive legacy for his grandson, but the criminal underworld isn’t done with him and won’t loosen their grip willingly.

While exploring the neighboring woods, 13-year-old John discovers an unfinished bunker — a deep hole in the ground. Seemingly without provocation, he drugs his affluent parents and older sister and drags their unconscious bodies into the bunker, where he holds them captive. As they anxiously wait for John to free them from the hole, the boy returns home, where he can finally do what he wants.
