Pirdy is accident prone. He has been denied insurance from every company in town because he is always getting hit or hurt in some way. On the day that he meets the lovely Ellen of the Yellow Cab Co., he also meets the crooked lawyer named Creavy. Pirdy is an inventor and when Creavy learns about elastic-glass, his new invention, he makes plans to steal the process. With the help of another con man named Doksteader, and the boys, he will steal this million dollar invention no matter who gets hurt.
The film concentrates on the camaraderie and the divisions between the troops as they ready for the big offensive. Told in a taut narrative, the men of the 101st, led by Van Johnson, wait out the winter in the Ardennes forest to confront the German army in what would be the last major offensive of World War II. The men are demoralized and trapped, with no hope of support from the Allies.
