In the filmsEdit
Anna had desperately wanted a child and had conceived quite a number of them with her husband, but all of them ended in miscarriage. They later adopted a daughter named Samara (Daveigh Chase); however, it soon becomes apparent that something is terribly wrong with Samara, as Anna begins to slowly go insane, driven by horrifying visions the young girl was supernaturally feeding her, either on purpose or out of lack of control of her powers. Anna and Samara are eventually admitted to a psychiatric institution. Later, at Richard's insistence, they are taken out. Thereafter, Samara is forced to live in their barn, away from the house, in hopes that it would stop Anna's visions. It does not, and the horses in the barn go insane, running to the beach nearby, where they drown themselves.
Eventually, Anna murders Samara at their getaway in Shelter Mountain by suffocating her with a plastic bag, and then dropping the body into a nearby well. However, little do the Morgans know, Samara survives in the well for seven days before finally dying. Shortly thereafter, Anna commits suicide by jumping off of a cliff, a death which Samara presumably plays a part in from beyond the grave.
In The Ring Virus, the Korean remake of the Japanese film, her name is Park Jung-Sook, and a very different character from Anna Morgan. She is the natural mother of the counterpart of Samara, Park Eun-Suh.
