Fine tale of British submariners during the Second World War, with John Mills as the vessel’s commander and a solid cast of crewmen, most notably Eric Portman as the hydrophone operator. The submarine Sea Tiger is sent to sink a new German battleship, but their quarry has escaped into the Baltic Sea, where they pursue, despite the extra distance and danger. Will they be able to destroy their target? And, if they do, will they manage to get back home again, even though they’ll be short on food and fuel? The quest for supplies leads to some land-based action, too.

  Recommended. Otto finds this one pleasing enough to relax.
