A drunken American, his daughter and an Old Etonian Englishman set out on a mission to destroy a German battlecruiser docked near pre-First World War Zanzibar. Action adventure, starring Lee Marvin, Roger Moore, Ian Holm and Jean Kent.

During World War One an English adventurer, an American elephant poacher and the latter's attractive young daughter, set out to destroy a German battle-cruiser which is awaiting repairs in an inlet just off Zanzibar. The story is based on a novel by Wilbur Smith, which in turn is very loosely based on events involving the light cruiser SMS Königsberg, which was sunk after taking refuge in Rufigi delta in 1915.
