Merchant seamen spend their leave in London.
Various shots of two young men in civilian clothes browsing around London. They go for a hamburger, walking around, sit in a park, smoke, chat, etc.
More shots of the three men (another man with the previous two) men walking around, getting out of a taxi, looking at shop windows. One man enters flower shop and buys flowers. He shakes hands with the other two and goes the other way - visiting a lady? More shots of the two men browsing around town. Sign on a building 'Merchant Navy Club'.
