For years, there have been reports of a large, black panther stalking the Glastonbury countryside. Crew at the festival say the cat is an open secret, although they disagree whether it is an escaped wildcat or fantastical apparition. Regardless, those who have seen the cat agree: it has shiny dark fur, strong haunches and an exceptionally long, thick tail.

The filmmakers race to find this cat in the lead up to Glastonbury Festival. But as the revellers descend, the cat becomes aware of their search and begins to watch them back.
