Advised by a blind fortune teller, Snail the Burglar steals from the estate of Master Cockle and sells the lootings to the young widow Miss Mussels. When an infuriated Master Cockle later traces his lost possessions to Miss Mussels' house, he drags her to the Court for a trial - but the odds turn out to be against his favour as the Court's Prefect becomes deeply infatuated with Miss Mussels.
