Titles read: "BRITISH SUBMARINE SUCCESSES IN THE MEDITERRANEAN".
Somewhere in the Mediterranean.
A British submarine returns from a patrol for a refit. It comes alongside its depot ship and the Commander goes aboard to hand in his reports. The submarine crew disembark and we see brief shots of them having showers and relaxing with a cup of tea on the depot ship.
Meanwhile, in the workshops we see men making repairs on the sub and fresh torpedoes being lowered in. The next trip is worked out by the Staff Officer of Operations and the Commander and the sub leaves port.
Activity in the submarine as it prepares to make a test dive. The submarine starts to submerge and the air escaping sends spray high into the air. Raising and lowering the periscope. The sub comes back to the surface and starts to fire her guns. She launches a torpedo while on the surface.
C/U of a tape machine, tapping out details of British submarine successes. Quick shot of skull and crossbones flag flying. Then we see prisoners from the U-93 German boat come ashore at a port and climb into the back of a truck. A white Ensign flag now flies below the skull and crossbones flag.
Cataloguer's note: not sure of significance of skull and crossbones - did the Germans fly it on their U-boats or did Allies put is there to show "this is the Hun"?
