YOUNG AND INNOCENT begins midway through an argument between a man and woman in a clifftop house. Next day Robert, who knows the woman, finds her dead on the beach but is later arrested when it is discovered she was strangled with the missing belt from his coat.
Robert manages to escape from the courtroom with the not unwilling help of Erica, the spirited daughter of the district chief constable, the Hitch trop of the couple brought together by fate to prove his innocence.
Waylaid by cafe brawls, a ghastly children's party and a collapsing mine, they finally discover the killer has a distinctive eye twitch. All this leads to the famous scene when the camera pans from Erica, across a hotel ballroom to the onstage blackface band and into the eyes of the drummer which start to twitch.
Many incidental pleasures sadly do not make a completely satisfying film.
Shelf or charity shop? Shelf as it's Hitchcock...
