When Lethierry's ship is wrecked on the Roches Douvres, a perilous reef, Deruchette promises to marry whoever can salvage the ship's steam engine. Gilliatt eagerly volunteers, and the story follows both his physical trials and tribulations (which includes a battle with an octopus), as well as the undeserved opprobrium of his neighbours.
