In the present day, immortal 1,000-year-old Doctor Parnassus (Christopher Plummer) leads a travelling theatre troupe that offers audience members a chance to go beyond reality through a magical mirror in his possession. Parnassus had been able to guide the imagination of others through a deal with the Devil (Tom Waits), who now comes to collect on the arrangement, targeting the doctor's daughter. The troupe, which is joined by a mysterious outsider named Tony (portrayed by Heath Ledger, Johnny Depp, Jude Law, and Colin Farrell) embark through parallel worlds to rescue the girl.

Featuring an amazing all-star cast and Heath Ledger’s last film performance, this is yet another singular cinematic masterpiece from acclaimed director Terry Gilliam (Brazil).
