Prison (The Devil's Wanton)

Math teacher Anders Henrikson, recently released from a mental institution, decides to exorcise his inner demons in film form. Henrikson persuades film director Hasse Ekman, a former student, to put together a film depicting an Earth in the hands of the Devil. Ekman passes the idea on to writer Birger Malmstein, who coincidentally is currently going through Hell on Earth with his prostitute lover (Doris Svedlund). She, in turn, is being tormented by her former pimp. The Devil's Wanton offers in embryonic form many of the themes explored in Bergman's later work.
