007: Road to a Million (2023) : 1x8

Three pairs remain in the explosive final episode of 007: Road to a Million. After being dropped high in the Swiss Alps the pairs face a gruelling off-piste hike across the freezing slopes in waist deep snow to a remote ice lake. They discover The Controller has rigged a question case with high explosives. The only way to continue is to shoot it down before it detonates, and their journey is over.
