Matt Scudder (Liam Neeson) is a former police officer who now works as an unlicensed private detective for various shady characters. One of them is drug dealer Kenny (Dan Stevens), who hires him to find out who kidnapped and brutally murdered his wife.
Scudder gradually begins to uncover clues leading to the kidnappers and discovers that this perverse crime is not the first, and certainly not the last, they have committed on the streets of New York. The serial killers are preparing to strike again, and for Scudder, who operates outside the law, a ruthless race against time begins.
