Previously filmed in England in 1919, the barnstorming Harry Maurice Vernon-Harold Owen play Mr.Wu re-emerged as a Lon Chaney Sr. vehicle in 1927. Chaney essays a dual role, as the titular Wu and Wu's honorable grandfather. After a lengthy prologue, it is established that Wu is a powerful, ruthless Chinese aristocrat who will stop at nothing to defend his daughter Nang Ping's (Renee Adoree) honor. When Nang Ping is seduced and abandoned by wealthy Briton Basil Gregory (Ralph Forbes), Wu begins plotting a horrible revenge, beginning with the killing of his own daughter (who goes to her fate with stoic resignation). He then captures Gregory's mother (Louise Dresser) and sister (Gertrude Olmstead), then forces Basil to watch as he prepares to subject the two women to unspeakable tortures. Wu is ultimately killed by Basil's mother, bringing this bizarre exercise in chinoiserie to a grim conclusion.
