Les anges sont parmi nous (1949)

Doctor Rougel is so absorbed in his work that he neglects his wife Nadine, who is subjected to the advances of Gérard Bérault, an admirer. A series of unfortunate events leads the doctor to doubt the fidelity of his wife, and he shamelessly throws her out. Michèle, the Rougels' little daughter, sick from despair, will eventually reunite her estranged parents.
