A mentally deranged concert pianist recalls his deceased love and decides to search for her. He believes he will be able to trace her in the underworld.

The young Isabelle escapes from the orphanage and she adopted by two chaps on a caravan. They then meet by chance the posh family of Louise- who runs away with the three adventurers when confronted with the reality of having to marry a Belgian with a large moustache and a bald head. They find a dog. Later Louisa degenerates into a minor moment of sexual hedonism and multiplexing with the two chaps before they are all overwhelmed by the Armageddon that was WWI.
