The Moral Sinner is a 1924 American silent drama film directed by Ralph Ince and written by Willis Goldbeck, Josephine Quirk, and Rita Weiman, based on the 1904 play Leah Kleschna by C. M. S. McLellan.

The film stars Dorothy Dalton, James Rennie, Alphonse Ethier, Frederick Lewis, Walter Percival, and Paul McAllister.

As described in a film magazine review,[4] Anton Kleschna, a crook, has his daughter Leah for an accomplice and utilizes Raoul Berton, son of a French general, as a tool.

Paul Sylvain rescues Leah from a burning building and she forms an attachment for him.

Raoul appears half drunk, and Paul hides Leah.
