The Marriage Chance (1922)

The film begins in a comic vein--bordering on farce--and continues so up to the point where Eleanor Douglas is about to marry young district attorney William Bradley. She drinks the glass of water offered to her by Dr. Paul Graydon and loses consciousness. Pronounced dead by Dr. Graydon, Eleanor is buried; but a cat, which also drinks from the glass, apparently dies, is about to be buried, but suddenly regains consciousness. Bradley hastens to exhume Eleanor's body, finds the coffin empty, and finally discovers Eleanor at Dr. Graydon's--lying on an operating table, still in her wedding dress, the doctor on the floor dead. Eleanor is suspected of shooting Graydon, but her sister confesses. The scene then fades back to the wedding, where Eleanor awakens from a fainting spell and realizes she has been dreaming.
