This is the story of C.I.O. Local 321 of the United Sheet Metal Workers in the shadow of Brooklyn Bridge, its self-made idealistic leader and organizer, Bart Pinza, and the present transition of a union from war to peacetime economy. The plant owner, playing upon the patriotism of the union members to break the union, taxes Bart's resources as he tries to maintain unity. But at the end of the war, latent grievances come to the fore -- and Bart is killed in his struggle against a politically ambitious member. The plot does not come through, but the author's characters are four-dimensional, human, sympathetic- and the book has a strong feeling of contemporary issues.
