No good comes from charting uncharted territory.
In this one, Liv and Ian talk about a group of nine people who went on a cross-country skiing expedition in 1959. Sadly, all nine of the skiers would be found dead after they never returned from their journey. How did this happen? Were the elements of nature too much? Was espionage involved? Perhaps aliens? All are a possibility.
Also, Ian becomes overwhelmed. Liv is underwhelmed.
