When Max, a newly married man, suspects that his wife may be cheating on him, he gives his faithful dog Dick orders to keep on eye on her when he's not at home.

Cécile Guyon is young Pierrot. He has fallen in love with the laundress, pretty Jane Renouardt. However, she wants more than a lover whose poor fashion sense impels him to dress as a stage clown. She wants jewelry, pretty clothes, and probably a string of poloponies, so Guyon robs his parents' safe and steals their life savings so he can run off with Mlle Renouardt.
