After religious spinster's missionary brother is killed in WWI Africa, dissolute steamer captain offers her safe passage. She's not satisfied so she persuades him to destroy a German gunboat. The two spend most of their time fighting with each other rather than the Germans. Time alone on the river leads to love.
