My Name Is Julia Ross 1945

Julia Ross secures employment through a rather nosy employment agency, with a wealthy widow, Mrs. Hughes, and goes to live at her house. 2 days later, she awakens - in a different house, in different clothes and with a new identity. She's told she is the daughter-in-law of Mrs. Hughes and has suffered a nervous breakdown. Is Julia really 'Julia', or is it true that she's lost all memory of who she is?
