The "little lady in the train" is Meg Lemonnier, cast as Irene, the flighty wife of a bourgeois Parisian. Hoping to escape her husband for a rendezvous with her boyfriend, she pretends to board the wrong train. Things take an unexpected turn when the train on which Irene is supposed to be riding is involved in a terrible accident. Presumed to have been killed, our heroine is able to dally a bit longer than expected with her sweetheart -- but she's in for quite a few surprises when she returns home to tell her husband the truth. Top billing in Une Petite Femme dans le Train was bestowed upon Henri Garat, who shortly after completing this film headed to Fox Studios in hopes of establishing himself as a Hollywood favorite (he didn't, but not for lack of trying).
