 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.
