Sezon 5

Led by Ant Middleton, 25 men and women - including an ex-SAS operator working as a mole - face the latest intense course, beginning with a swim to a remote Scottish island.

The recruits are pushed to control their aggression, as they're trained with guns and take part in hand-to-hand combat, in an episode exploring loss, loyalty and self-control.

The recruits take on the intense close-combat murderball and surf immersion - a notorious water beasting that simulates water torture.

The recruits' grit is tested as Jay's undercover status is revealed and he launches a brutal beasting to expose the weakest in the group.

The recruits are stalked across the Scottish Highlands by a military-trained hunter force, before facing extreme interrogation on limited sleep and rations. Who will crack?

The last six recruits face deep interrogation and a day of sickeners, including `drownproofing' - simulated drowning. Only the physically and mentally elite will make it through.
