It is Detroit during World War II, and the U.S. is trying to out-manufacture the Germans and Japanese. Workers have been brought in to replace the men fighting in the war. For the first time Southern whites and blacks are working together. But with the black market, rationing, and the Mafia; Detroit is also a powder-keg. Through this tense world cuts a killer, a self-appointed soldier savaging the defenseless. Lieutenant Zagreb's job is to catch the killer, keep the city from exploding, and save his own troubled soul.
