In December of 1994, Hitler launched 200,000 soldiers and over 500 tanks against the allied lines in Belgium in a desperate attempt to stave off defeat. Caught off guard, the allied forces were pushed back, with the new frontlines forming a bulge into their controlled territory. For the next 41 days - and amid brutal winter conditions, the two sides would engage in fierce pitched battles that would eventually claim more than 160,000 casualties and determine the outcome of the war. The film details how the tactics of the allied forces repelled this massive offensive and broke the back of the German army.
