This episode of the serial Judex does contain a kidnapping, trespassing, and a sexy swimsuit, but is mostly pretty staid family fare overall. As the plot develops, we become more concerned with family relations than with crime and revenge.
The movie begins at a Mediterranean estate, where Madame Tremuese (Yvonne Dario) has brought Jacqueline (Yvette Andréyor), Robert (Édouard Mathé), Le Petit Jean (Olinda Mano), and the Licorice Kid (René Poyen). Apparently, they are all relaxing and enjoying themselves, and also feel reasonably secure from the scheming of the villains, since the kids are allowed to play unsupervised, and the adults spend their time at the seashore. Next door, we learn, Judex (René Cresté) has brought Kerjean (Gaston Michel) and Favraux (Louis Leubas), who also needs some time in the sun to recover his sanity after his long imprisonment below ground. Judex reassumes the title Jacques de Tremeuse and arrives at his mother’s estate, announcing that he has only just returned from the colonies, but both Jaqueline and Le Petit Jean feel they have seen him before. It is decided to invite Cocantin (Marcel Lévesque) down to see them as well, and this gives Diana Monti (Musidora) and Morales (Jean Devalde) a chance to tail him in hope of finding Favraux.
