As departure day approaches, Ewan resurrects his old California police bike while Charley brings a 1970s rust heap back from the dead.

Fresh off the ferry, the guys travel through the Netherlands and Germany to visit Charley's mom's hometown before heading to the Danish islands.

In a scary setback, Ewan's bike gives way from underneath him. A local Swedish biker club comes to the rescue. Then it's off to meet a mermaid.

The guys temporarily ditch their bikes to fly to Svalbard, an archipelago in the Arctic where the effects of climate change are glaringly real.

Ewan and Charley meet a man with a fascinating connection to the Lapland forest in Finland and encounter two crazy motorsport events.
