SAS: Who Dares Wins: Season 4, Episode 5

4 - 5: Pressure

Four men and five women remain in the competition, but the training staff are determined to throw everything at them in a final effort to expose any weaknesses before next week's final challenge. The recruits must cross a 200-metre gorge and swim beneath the ice on a frozen lake, before they are pursued by hunters with dogs through a perilous valley at night.
