Impressions of a great city from daybreak to dusk. A roving camera and smooth theme music say more than words. London's traditional sights - Buckingham Palace, Trafalgar Square, the Royal Parks, the Zoo, etc., await their visitors in the early morning. While a young motor-cyclist hurries by, to work on the pleasure boat he conducts along the Thames; a Beefeater goes on duty at the Tower; and the visitors hurry into London by bus and coach. The film conjures up the mood of a variety of London scenes and events throughout the day until a sightseeing-bus tour gives the visitor a last chance to catch up by night on anything he may have missed during the day.
