The team travels to Parys Mountain on the island of Anglesey. They will investigate if a connection between two bronze aged copper mines can be found. Their efforts will be complicated by the crumbling nature of the workings. Only recently pumped dry the expectation is the whole Bronze Age mine operation will collapse in on itself in a matter of months. This is the ultimate one shot expedition.

The team investigates a cave system recently discovered under the Forest of Dean on the border of England and South Wales. They are looking for ways to identify and date a series of bones possibly dating to the last ice age found over the last 13 years. Conditions are arduous and the expedition soon takes a heavy toll on a number of team members.
