When Jimmy is made redundant from his tunnelling job and needs money quickly to hire a lawyer to help him with a custody dispute over his young daughter Sadie, he comes up with a scheme to rob the cash-rich vault of the nearby Nascar racing track where he has been working. To access the safe they need the skills of Joe Bang (played by Daniel Craig), who is currently incarcerated in the local prison, who brings into the gang his redneck brothers, who are no criminal masterminds.
A seemingly estranged father (Michael Shannon) appears to kidnap his own son from what turns out to be a cult and takes him on the road… But why? And where are they going? And why was the boy revered by this cult?
The details slowly emerge as the chase progresses and we learn more about the boy, Alton, and certain powers he seems to posess. But we never quite understand them, and the director (Jeff Nichols) keeps playing with the audience’s understanding of what may be going on.
