The Goodies, after being rejected from having their own legal radio station because their submission was too late, decide to start their own pirate radio station outside the five-mile limit. They then start a pirate post office using various methods of delivering mail. The power unfortunately goes to Graeme's head and he becomes a megalomaniac, trying to tow the whole of Britain outside the five-mile limit to create a "pirate state". Thankfully, he sinks his submarine by accident and is forced to give the whole thing up.
