Advertised as "A Romance of the Moors," the film stars Lil Dagover as Barbara, a servant's daughter. Wealthy young Viscount Heinrich (Paul Hartman) is in love with Barbara, but their marriage is opposed by the boy's guardian Old Greishaus (Arthur Krausmack), who threatens to cut off Heinrich's inheritance. There are many heartbreaks and disappointments ahead for the two lovers, but in the end Right prevails. Variety's critic not only panned At the Grey House but also skewered the introductory comments made by the manager of the New York theater which ran the film.
