The estuary is London's last wilderness. In that region (the size of London itself) the rules are different from the rest of the river and the danger is high.

Londoners are used to seeing the flow of the river Thames from the embankments and bridges of Central London. The river is admired as a distant visual element. Find out what happens when a group of urbanites decide to tackle the river from the water itself. What they are in for when they "leave the certainty of the shore" as the narration goes. Based on the river Medway in Kent, UK, the filmmakers travel downriver to meet the Thames. The voyage becomes an emotional and shamanic experience as well as a geographical one.—Paul Burns
