Barnaby Bear learns about Hurley Lock on the River Thames and discovers how it works. He helps a lock keeper to operate the lock and learns how opening and closing the lock gates allows a boat at a lower level on the river to be taken up to a higher level to join the river ahead. With Brian the lock-keeper, Barnaby looks at the course of the River Thames on a map. They identify the source of the river and follow it on the map to the mouth of the river and the sea. Barnaby also takes a trip on a pleasure cruiser as the river flows through London. He travels under some of the bridges. Barnaby takes a flight on the London Eye and admires both the view and the width of the river from the top of the wheel.
