Joanna Lumley travels to Tromso, Norway, chasing a lifelong wish to see the Aurora Borealis before she dies. The film follows her into the Arctic winter, camping out and hiking through snow to reach vantage points away from town lights, enduring the cold for a clear view of the sky. Along the way she meets the region's wildlife, including reindeer and Arctic foxes, and talks with people who live year-round in that landscape. When the lights finally appear, the camera holds on the display long enough to show the green, blue, and purple bands shifting overhead, and Lumley's reaction is unscripted rather than narrated. Interwoven with the travelogue is a plain explanation of what causes the aurora: charged particles from the sun colliding with gases in the upper atmosphere. There is no expedition drama or scientific deep-dive here, just one woman's patient wait for a specific natural event and the trip it takes to get there. The Northern Lights themselves are the payoff the whole film is built around.
