Following a format evident in many other seaside publicity film, The Belle of Kent opens by demonstrating the resort's good transport links and telling the viewer of some of the history of the town. The film goes on to show various sights around Margate, including the Theatre Royal, the old town and the harbour. Described as a "five in one resort" Margate's five sandy bays are featured, with donkey rides available and formal gardens on the cliff tops. Excursions are suggested to the nearby "Cinque Port" of Sandwich, and Canterbury Cathedral. Back in Margate, the sundeck at Palm Bay offers refreshments, a bandstand and swimming at the lido. A 'Bathing Beauty' contest is held at the lido; the contestants pose for the judges in swimwear by the side of the pool. Day trips by boat to Boulogne are available, and the film illustrates this with scenes around the French town. Back in Margate again, evidence of the seaside variety shows and performances available is provided, with Dickie Valentine and Petula Clark making appearances. To end the film, the audience is reminded of the traditional pleasures of Margate, with its beach, Punch and Judy shows, fairground rides at the Dreamland amusement park and firework displays.
