The Uninvited is a 2009 American remake of the 2003 South Korean horror film A Tale of Two Sisters. It is unrelated to another 2003 Korean horror film and a 1944 American film, both of which have the same name.
Anna (Emily Browning) has been in a psychiatric institution for ten months, following her suicide attempt after her terminally ill mother died in a boathouse fire. Now, she is being discharged and has no memory of the actual fire, although she is frequently plagued by nightmares from that night. While packing, Anna is startled by a disturbing, talkative patient who stays in the room across from hers. Shortly after, she leaves with her father, Steven (David Strathairn), a writer who has dedicated his latest book to Anna and her sister.
