A tough town in a tough time, Detroit during World War II was where the United States furiously tried to outmanufacture the Germans and Japanese. Industry imported workers to replace men gone to war-with Southern whites and blacks working side by side for the first time. Through this tense, troubled world cuts a killer, a self-appointed soldier savaging ordinary people, the defenseless. Lieutenant Zagreb's most important job is to keep the city from exploding, but his job doesn't stop there. He must catch a mad killer with a cop roster of 4-Fs and near-retirees, and he has to save his own soul. But, he can't succeed at all three.
