New Orleans, 1944. Justine Byrne works at a small factory in the bayous of New Orleans to keep her head above water. Soon though, Justine begins to suspect that the carbon parts she assembles on the factory line might have something to do with a top-secret government initiative—The Manhattan Project. But Justine is not the only one to realize that the factory is much more than it seems, and German saboteurs will do anything to put the factory out of commission. With no one to trust, it will be up to Justine to figure out who is responsible and protect her coworkers, her factory, and her country from a war that is suddenly very close to home.
