Plot
Paul Lavond (Barrymore), who was wrongly convicted of robbing his own Paris bank and killing a night watchman more than seventeen years ago, escapes Devil's Island with Marcel (Henry B. Walthall), a scientist who is trying to create a formula to reduce people to one-sixth of their original size. The intended purpose of the formula is to make the Earth's limited resources last longer for an ever-growing population. The scientist dies after their escape.
Lavond joins the scientist's widow, Malita (Rafaela Ottiano), and decides to use the shrinking technique to obtain revenge on the three former business associates who had framed him and to vindicate himself. He returns to Paris and disguises himself as an old woman who sells lifelike dolls. He shrinks a young girl and one of his former associates to infiltrate the homes of the other two former associates, paralyzing one.
