Radiopiratene plot
After the rift between his parents, Karl Jonathan leaves with his father to his native village of Skjellerute. Upon arrival, they soon notice that things are not quite right. Skjellerute has been transformed into a strict society where children cannot be themselves. Karl Jonathan soon befriends the girl Sisseline and together they decide to revolt against this 'model village'. They do this with the help of a pirate transmitter that they breathe new life into. The pirate transmitter does indeed work as a disruptive transmitter in the perfect Skjellerute, and the inhabitants band together to silence the pirate transmitter for good.
