After terrifying audiences in last year's thriller The Conjuring, a new trailer for the upcoming spin-off Annabelle showcases the origins of the haunted doll.

Years before paranormal investigators Ed and Lorraine Warren (played by Patrick Wilson and Vera Farmiga in The Conjuring) captured Annabelle, John Form (Ward Horton) picks up this vintage doll as a gift for his wife Mia (Annabelle Wallis). Their lives unfold into a horrific nightmare when a satanic cult invades their home. Check out the latest footage from director John R. Leonetti's horror spin-off, which hits theaters October 3.

She terrified you in The Conjuring, but this is where it all began for Annabelle. Capable of unspeakable evil, the actual doll exists locked up in an occult museum in Connecticut-visited only by a priest who blesses her twice a month. New Line Cinema's supernatural thriller Annabelle begins before the evil was unleashed.

John Form has found the perfect gift for his expectant wife, Mia-a beautiful, rare vintage doll in a pure white wedding dress. But Mia's delight with Annabelle doesn't last long. On one horrific night, their home is invaded by members of a satanic cult, who violently attack the couple. Spilled blood and terror are not all they leave behind. The cultists have conjured an entity so malevolent that nothing they did will compare to the sinister conduit to the damned that is now... Annabelle.
