In the heat of late summer, two New Orleans families—one black and one white—confront a storm that will change the course of their lives.

SJ Williams, a carpenter and widower, lives and works in the Lower Ninth Ward community where he was born and raised. Across town, Craig Donaldson, a Midwestern transplant and the editor of the city's alternative paper, faces deepening cracks in his family. When the news of the gathering hurricane spreads—and when the levees give way and the floodwaters come—the fate of each family changes forever.
