Ten questions stand between brothers James and Joey and £1 million as they face a gruelling trek across the Scottish Highlands. A familiar Rolls Royce, a race through Venice and a dramatic encounter in an Italian palazzo await.
An obstacle stands in the way of the eight remaining duos; the duos leave the Highlands and embark on an intense race against time.
The seven remaining duos are scattered all over the world; Beth and Jen explore the controller's world; the Bone brothers find themselves in the Amazon rainforest.
To search the Atacama Desert, Kamara and Josh must cross a train station, a solar farm and remote villages; Josh deals with his trauma.
After an epic climb in Chile, Kamara and Josh must answer a tough question; the controller welcomes a new duo, Grace and Daniella, to St Mark's Square in Venice; Tanaka and James dive into a hidden cave.
The Bone brothers are marooned on a stranded catamaran with only a bottle of rum; James and Sam continue their adventure in the Chilean desert.
