In filmmaker Mike Flanagan’s adaptation of Stephen King’s Doctor Sleep, as well as the follow-up to Stanley Kubrick’s The Shining, Rose the Hat is the leader of a nomadic tribe called The True Knot. Rose and Co. hunt telepathic children who have the ability to shine a la Danny Torrance in The Shining and Doctor Sleep’s analogue, Abra Stone (Kyliegh Curran). Rose and her followers torture such children and feed off their essence, which they refer to as “steam.” This allows Rose and her friends to live forever, while increasing their own individual powers in the process.
