Maskerade (2009)

Sinopsis

A television recording of the stage adaptation of Terry Pratchett's novel, produced by Divadlo v Dlouhé. Granny Weatherwax and Nanny Ogg, the greatest witches on Discworld, set out to enjoy an evening at the Ankh-Morpork Opera, where their fellow Lancre native and potential third witch, Agnes Nulli, sings in the chorus. But strange things are happening at the Ankh-Morpork Opera House, and not just in the accounting department. Opera employees are falling dead from the fly loft, box number 8 cannot be sold because it has been reserved by a mysterious figure wearing a white mask, and the newly appointed director is receiving strange letters from a certain Ghost of the Opera.
