Rose and Allnutt, 2 English people in Africa, decide to take the African Queen down a river, the Ulanga River, full of rapids, and blow up a German ship on the lake to help the war effort. They get down the rapids alive – Rose steers and Allnut mans the engines. They make a torpedo – or a couple of them. They are aiming for the ship when a freak storm sinks the African Queen. They are rescued by the Germans – handed over to the English Navy and then the English Navy sink the German ship. Rose and Allnutt go off together to get married.
