The show takes a spooky turn as we go on a ghost hunt through the natural world. Sebastian shares his adventures finding fossils – the traces of animals that once lived, and Rutendo talks about her experiences in The Cradle of Humankind, the South African UNESCO World Heritage site containing early human fossils.

Deep in the Peruvian Amazon there is a species of wild dog so rarely sighted it has become known as the ‘ghost dog’. We hear from Renata Leite Pitman, one of the few scientists to successfully track down and study the elusive creature as it moves quietly through the forest.

Gravedigger turned ecologist Dan Flew leads Rutendo and Sebastian through Bristol’s Arnos Vale Cemetery in the dead of night, for a close and thrilling encounter with some of the UK’s rarest bats.

We venture to the world’s most northerly permanently inhabited place, Svalbard, in the Arctic Circle, where TikToker Cecilia Blomdahl reveals the magical secrets of this isolated yet beautiful landscape, on a trip out on her boat with her dog Grim.

And we hear rare recordings of the Northern White Rhino, sadly now extinct in the wild, a recently departed ghost of a more biodiverse world.
