In the eastern United States, Charles City, located in the suburbs of Boston, is like a paradise forgotten by the legal system. The working class of Irish descent accounts for a large proportion of the city. The poor living conditions and the breathless pressure in the area make people take risks. Bank robberies happen from time to time, and everything becomes crazy and hopeless. One morning, the beautiful bank manager Claire Gisse (Rebecca Hall) encountered a group of robbers wearing skull masks, and she was taken hostage. Strangely, Claire survived unexpectedly in the end, as if the accident of this morning had never happened. One day, she met Doug McCree (Ben Affleck), a tall and handsome man, and a wonderful fate unfolded, and the fate of the two also changed... This film is adapted from the original work of Chuck Hogan.
