An annual Swedish Christmas calendar television series.

The Olsson family, weary of city life, rents what they believe is a house in the country for a traditional Christmas. Instead, they arrive at the grand castle Greveholm, where the children soon discover the castle is not like any other – it is haunted.

A behind-the-scenes documentary about the Christmas calendar 'Mysteriet på Greveholm', a very technically advanced TV production for its time.
