Jarvis goes into hospital for a routine procedure, and the anaesthetic gives him some very strange nocturnal visions.

As Dr Ed Patrick administers the anaesthetic, Jarvis is transported far, far away. One moment he's on a Scottish lighthouse at midnight with artist and writer Peter Hill, who spent time as a lighthouse keeper in the 1970s.

Then, in the blink of an eye, he's in a blizzard in the far north of Norway with Sunniva Sorby and Hilde Fålun Strøm, who became the first women in history to overwinter solo in the Arctic.

The visions just keep coming as ice turns to fire, and Jarvis finds himself on the top of a mountain watching forest fires burn through the night with author Philip Connors who spends half of every year as a fire lookout high up in the mountains of New Mexico.

In a night of vivid encounters, everyone Jarvis meets has stepped away from their every day lives, to live life on the edge.
