Plots(1)
Before the bomb can be perfected, Hitler's death and Germany's surrender remove one enemy from the equation. But Japan remains. Day One builds quietly to a shattering climax, as the scientists who developed the bomb out of patriotic fervor witness its grisly consequences. (official distributor synopsis)
