Steel Town top-bills Ann Sheridan, but the bulk of the story is carried by John Lund. Cast as Steve Kostane, the nephew of a steel-plant proprietor, Lund must prove his value to by learning the business from the ground up as a steelworker. It isn't easy: throughout the film, Kostane is weighed down by personal problems that threaten to overwhelm him -- and to financially ruin the little steel town where he works. Sheridan does her usual competent job as "Red" McNamera, the down-to-earth restaurant cashier who ends up the romantic bone of contention between Kostane and veteran open-hearth worker Jim Denko (Howard Duff). A heart-pounding climax finds Kostane rescuing Red 's father (William Harrigan) from a horrible fate. Steel Town was lensed on location at California's Kaiser-Fontana steel plant.
