Their Last Night.

Arriving in Paris, Madeleine Marsan rents a room in a guesthouse where she makes the acquaintance of Pierre Ruffin, a respectable municipal librarian. Through Pierre, Madeleine finds work as a schoolteacher and soon realises that she is in love with him. Then she discovers that Pierre is in truth the head of a band of crooks. Caught by the police after a failed robbery, Pierre manages to escape. With Madeleine’s help, he goes on the run.
