After completing his training, Homer is assigned to a submarine, the USS Cheyenne. He is thrilled to be part of a crew and feels a sense of pride in his new role. However, he quickly realizes that life on a submarine is not as glamorous as he imagined. The cramped quarters and strict discipline challenge him, and he begins to feel homesick.
