A mysterious stranger, Meisner, arrives in a northern Swedish town in 1820, calling himself a magnetist - an amalgam of hypnotist and healer - and claiming he can cure diseases un-treatable by doctors. Ignoring the objections of his colleagues, Dr. Selander allows Meisner to cure his blind daughter, Maria, who not only regains her sight, but also falls in love with the charismatic magnetist. Dark secrets and repressed memories start to emerge, amidst the love between father and daughter, man and woman.
