Teenager Ellis and his best friend Neckbone live on the river with their parents. During an expedition to a nearby island, the boys stumble upon a charismatic fugitive called Mud, who is hiding in an abandoned boat. Mud takes the youngsters into his confidence and reveals that he is awaiting the arrival of his girlfriend Juniper. However, he cannot make direct contact with Juniper because she is being watched by violent men, so Mud asks Ellis and Neckbone to pass on a message for him.
