My Name Is Julia Ross

In London, Julia visits a new employment agency and is recommended for a live-in secretary position by Mrs. Sparkes. Mrs. Hughes approves the arrangement and insists that Julia move in that very night. Julia leaves her old life behind and begins her new role at the wealthy widow’s house.

Two days later, Julia wakes to find herself imprisoned at an isolated seaside estate in Cornwall. She learns she is being passed off as Marion, the wife of Ralph Hughes, and the staff pretend she has suffered a nervous breakdown. Her pleas for help are ignored and every escape attempt is thwarted.

Julia is treated as Marion, not as herself, by the household. The staff refuse to acknowledge her real identity and monitor her movements closely. The sense of danger grows as she is kept under constant watch.

Desperate for help, Julia writes a letter to her friend Dennis Bruce and hides it where it can be found. She hopes the letter will reach someone who can rescue her from the estate. The plan relies on someone discovering the message despite the house's attempts to control her fate.

That night the Hugheses substitute a blank sheet for Julia’s letter and allow her to post it, unaware that she has anticipated their trick. She has already written a second letter, asking Dennis for urgent assistance. The deception only tightens the net around her.

Julia discovers a secret passage to her room and overhears Ralph confess that he murdered his wife and disposed of the body in the sea. The confession confirms the danger she faces, yet she is unable to act openly while under surveillance. Her knowledge is momentarily useless as the fake doctor remains in the house.

Julia realizes the 'doctor' she confided in is in on the plot with Mrs. Sparkes and others. He is dispatched to London to intercept the letter she has written. The plan shows how deeply the conspiracy runs within the estate.

The real doctor arrives the next morning, but Julia suspects he is not legitimate. He recommends she be taken to a hospital, yet Mrs. Hughes persuades him to return the following morning. The scene heightens the tension as escape remains blocked.

To ensure she cannot be removed, her captors plan to make it look like she has committed suicide. The doctor’s intervention must be delayed while the plan is put in motion. Julia realizes she must act quickly to survive within the trap.

Julia throws her gown out the window to fake a death and hides in the secret passage. When the doctor drives up, Mrs. Hughes delays him so Ralph can reach the body first. Ralph lifts a rock to confirm her death, but Dennis and a policeman arrive, alerted by Julia's second letter.

The fake doctor is intercepted in London while attempting to intercept the very letter he was supposed to seize. Dennis and a policeman, alerted by Julia’s letter, close in on the conspirators. The web of deception begins to unravel rapidly.

Ralph tries to flee, but Dennis and the policeman shoot him down. The confrontation ends his murderous scheme and confirms Julia’s safety. The estate loses its oppressive force as law takes its course.

Julia and Dennis drive away together, finally free from the Hugheses’ treachery. They talk about marrying and starting a life together. The perilous nightmare concludes as they head toward a hopeful future.
