In this obscure silent crime drama, veteran action hero George Larkin played Shadow Brice, a crook searching for the famous Denman diamonds. Shadow wins the confidence of Daphne Denman (Charlotte Morgan), but the jewels are stolen by rival gangster Burley Walters (Arthur Morrison). After a furious chase through the streets of San Francisco, Shadow wrests the diamonds from Walters, revealing himself to be an undercover secret service man. Stop at Nothing was produced and directed by Charles R. Seeling from a screenplay by Larkin himself.
