Strangers in the House

Hector Loursat (Raimu), a brilliant but troubled lawyer, lives with his estranged daughter Nicole in a vast and shabby mansion. A corpse is discovered in the residence, and Nicole, who leads a secret life with a group of young people, becomes the prime suspect. As Hector defends one of the suspects, Emile, he uses his unorthodox strategy to reveal the true killer, Luska (Marcel Mouloudji), who framed Emile for jealousy over Nicole's relationship.
