The prodigal and mysterious motorcyclist Luke (Ryan Gosling) unexpectedly reunites with his old lover Romeiah (Eva Mendes) on the performance stage of a carnival. Luke is desperate to renew his relationship with Romenia, but is surprised to find that Romenia has not only cohabited with another man, but also has an infant son with him. So Luke, who had originally planned to leave, wishful thinking, stayed in the town in order to take care of his son and Romenia. To make up for the guilt he felt for his son, Luke decided to rob a bank with a man he met in a small town. During the last operation, Luke is besieged by young patrolman Avery (Bradley Cooper). Young Avery had a loving wife and a son who was also in infancy. Luke and Avery, two men with very different identities, seem to have no connection, but neither of them has imagined that because of this robbery, they are inextricably linked.
