After a botched bank robbery lands his younger brother in prison, Constantine "Connie" Nikas (Robert Pattinson) embarks on a twisted odyssey through the city's underworld in an increasingly desperate-and dangerous-attempt to get his brother Nick (Benny Safdie) out of jail.

Over the course of one adrenalized night, Connie finds himself on a mad descent into violence and mayhem as he races against the clock to save his brother and himself, knowing their lives hang in the balance.
