Watch on SFlix. The short film shows real footage of the city of London and the area around the River Thames. The commentary is spoken by a member of the London Water Police in German with an English accent. Together with the commentator, the viewer takes part in a boat trip on the Thames, which begins above London and then shows the western suburbs, the government district, the West End, the south bank of the Thames, the city and the harbor area of the metropolis.
