SAS: Who Dares Wins

Betrayal (3x4)

Air date: Jan 28, 2018

The remaining recruits are challenged to dive backwards and blindfolded into a reservoir from a gangplank 10 metres up, before moving on to the most psychologically demanding stage of training - resisting interrogation. A simulated capture puts the friendship between two of the group to the test, as they are pushed towards betraying one another.
