When Hurricane Katrina hit New Orleans in 2005, thousands of inmates at Orleans Parish Prison were left behind as the water rose. Guards had evacuated their own families first, and prisoners describe being locked in flooding cells with no food, no water, and no working lights for days, some standing on bunks and toilets to keep their heads above the waterline. The film gathers eyewitness accounts from former inmates and correctional staff who lived through the collapse of the facility, alongside footage of the prison's condition in the storm's aftermath. It traces what happened to the people the official evacuation plans never accounted for, and asks how a jail housing thousands could be left off the city's rescue list while buses ran for other stranded residents. The result is a account of the disaster's least-covered corner: the people the flood locked in rather than out.
