University student Andy Shaeffer has been doing everything he can to avoid being drafted into the military, even though the United States is not at war. But when his girlfriend, Susan Daniels, becomes so upset at what she regards as his cowardice that she breaks up with him, Andy's grades fall and he loses his draft deferment. And when Andy arrives in basic training, his commanding officer makes it a personal mission to turn Andy from a spoiled, immature boy into a man.
