After a series of traumatic childhood events, a psychosomatically deaf, dumb and blind boy becomes a master pinball player and the object of a religious cult.
(This is not without cinematic precedent either, since in Ken Russell's allegorical Christ story, Tommy, it's Russel's own hand that deals the death blow to the Mary figure, and it's his foot that kicks his "messiah" in the head.)
For the uninitiated, Lisztomania (advertised as "the erotic, exotic, electrifying rock fantasy ? it out-Tommy's Tommy") is a colorful, cheeky, deliberately anachronistic film that portrays Franz Liszt (Roger Daltrey) and Richard Wagner (Paul Nicholas) as 19th century rock stars.
