Young and Innocent

On a stormy night at a coastal retreat, Christine Clay argues with her jealous ex-husband Guy. He accuses her of having an affair and she slaps him before he storms off; his eyes twitch violently as he leaves.

The next morning, Christine's body washes ashore after the storm. Robert Tisdall recognizes her and runs for help as two young women watch him flee the scene.

Christine was strangled with the belt from a raincoat, and Tisdall's raincoat is missing. He claims his coat was stolen, providing a potential clue but also a troubling alibi.

Scotland Yard detectives grill Tisdall all night, insinuating an affair. When told of Christine's will, he faints and is revived by Erica Burgoyne; overwhelmed, he escapes during overcrowding in the courthouse by riding on the running board of Erica's Morris car.

Tisdall slips into Erica's car after the escape, and she drives him to a filling station where he pays for petrol. He then asks her to give him a ride, and she gradually comes to believe in his innocence.

Erica and Tisdall, now on the run, are spotted together and forced to stay ahead of the police. Erica becomes convinced of his innocence and resolves to help him clear his name.

To prove his innocence, they decide to locate the coat that may tie it to the crime. They trace Tisdall's coat to Old Will, a homeless china-mender, who reveals he received the coat from a man with twitchy eyes, though the belt is already missing.

Erica is separated from the others and taken in by the police; her father, the Chief Constable, resigns rather than arrest her. Later, a pocket from the coat contains matches from the Grand Hotel, suggesting a hotel connection to the killer.

Erica and Will go to the Grand Hotel to follow the lead. They discover Guy, the ex-husband, is the drummer in the hotel ballroom, performing in blackface and showing twitching eyes.

Guy's performance falters when Old Will is recognized in the audience and police tail him. He takes a medicine to steady the twitching, but it makes him sleepy; during a break, he loses consciousness.

Revived and confronted, Guy confesses to the murder and breaks into hysterical laughter. The truth about the crime is revealed, and the chase ends with Tisdall likely exonerated and Erica's involvement explained.
