Titles read: "NAVY SINKS THREE U-BOATS".
Several shots of a British naval convoy at sea. Brief shots of U-boats as commentator talks of German planes and U-boats attacking a British convoy of over 30 ships. German planes drop bombs. Various shots of warship guns firing. Footage taken by an amateur cameraman on one of the destroyers shows explosions in the sea around the U-boats and a U-boat sinking - very dark and poor quality "but they are the real thing".
The amateur footage freezes for a few seconds so we can make out some blobs in the water, which we are told are U-boat survivors.
