C/U of three men, two of whom are wearing headphones. They are possibly working in some kind of control centre for river traffic. One of the three talks into a microphone or some kind of recording device. C/U of a map. It seems to be the map of a river. In bottom left hand corner text reads: Northforeland Radio - Advance Warning MSCS (?).
Camera pans across the map. One of the parts focussed on has the name "Broadness Point". The map seems to have been painted on to a blackboard and the men who work in the centre write things on a glass surface placed over the map with coloured crayons. There is also information on the board as to the time of sunset and sunrise.

High angle shots of tug boats moving through water. High angle shots of vehicles on board the Ernest Bevin Ferry. They are on the top deck of the boat in the open air. Various shots of the ferry on the move. Camera zooms in to shot of the cars and lorries on the top deck of the ferry.
Various shots of shipping. Ships and tugs seen include: Pentworth (coastal tanker), Wightstone, Swifstone, Ionia, Touchstone, Challenge and Valiant. Most of this footage probably takes place on the River Thames.
