In the 1920s, actor George Valentin (Jean Dujardin) is a bona fide matinee idol with many adoring fans. While working on his latest film, George finds himself falling in love with an ingenue named Peppy Miller (Bérénice Bejo) and, what's more, it seems Peppy feels the same way. But George is reluctant to cheat on his wife with the beautiful young actress. The growing popularity of sound in movies further separates the potential lovers, as George's career begins to fade while Peppy's star rises.
