She flees with her old beau Colonel John (Warner Baxter), but Eric and Sir George are not far behind. Finally, the trail ends in San Francisco where Sir George enlists the help of Charlie Chan (EL Park) to finally unveil the truth...
As an early talkie it is unfortunately marred by awkward dialogue, especially at the start as the actors almost fight to get their lines out, and very stiffly too (though noticeably improves later on). However, this is a very decent film with some epic settings and a good involving story. You won't see much of Charlie Chan (though he is for once played by an Asian actor), though you will see Boris Karloff in his first sound role.
