SAS: Who Dares Wins

In the series finale, the last recruits are subjected to all kinds of punishing interrogation techniques. In the most feared phase of the course, they receive severe punishments, being buried alive, and thrown in water tanks, to force a confession.

After a beasting on base, the teams are pushed to their physical limits as they race to pull vehicles weighing 1000kg from the sand while under indirect simulated fire. Calls from home unsettle some and prompt an honest reflection of the cost of war.

After a set of tasks designed to test trust, including hand-to-hand combat and a terrifying abseil, Shylla's pushed to confront how a lifetime of racism has made her withdraw.

The recruits try a seven-metre backwards dive and face an elimination sickener on a major sand dune. After hand-to-hand combat in murderball, they're ambushed while driving back.

The remaining recruits face the final stages which consist of an interrogation and a brutal sickener. They must prove that they have both the mental and physical strength to complete the process.

The recruits are on the run across the punishing landscape, pursued by a military-trained hunter force, in a real life game of cat and mouse where only the strongest will make it through.

The recruits work in pairs as they tackle the threat of chemical warfare and execute a fast-paced extraction in near-freezing water. Then, it's time for brutal hand-to-hand combat.

The recruits must master their emotions under extreme pressure - from a scary backwards dive at night to an illusion jump. There is a further shock as the mole in their midst is revealed.

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.

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

The remaining men and women's final challenge is also the most psychologically demanding: resistance to interrogation, as they're subjected to stress positions, white noise and relentless grilling.

The remaining recruits must cross a 200-metre gorge, swim beneath the ice on a frozen lake and navigate a perilous valley at night, while trying to avoid capture by a local hunter force and their dogs.

This episode is about trust. The recruits are teamed up in pairs, then take a free-falling abseil into a rocky gorge and plunge into freezing water, with their partners responsible for saving them.

With the conditions deteriorating, the recruits must negotiate beastings in the snow and a night out in a blizzard 3000 metres above sea level, while the DS increase the psychological pressure on them.

Eighteen recruits down, seven to go... and it's the most demanding final phase the instructors have ever designed. Some recruits have to give up, others are culled. Will any of them pass the course?

The recruits must dive 10 metres into a reservoir - backwards, and blindfolded. And then they're captured and intensely interrogated in an extreme test of mental resilience, trust and moral judgement.

The recruits race each other across sand dunes in the Sahara and must cross a valley at night while avoiding hunter teams who are tracking them with dogs

The recruits must abseil 200 feet off a dam and climb a mountain in blistering heat with 40lbs on their backs

In the final episode, the remaining recruits undergo the most psychologically demanding 24 hours of the course: the resistance to interrogation phase, as they are abducted and intensively interrogated

The directing staff apply pressure to the last eight recruits, exposing hidden personality traits before sending them into a gruelling 12-hour jungle mission high in the Andes

The remaining recruits' trustworthiness is tested, as the directing staff sow distrust among them and ask them to identify their least trustworthy teammates, before a forward abseil trust exercise

Chief Instructor Ant and his elite team test whether the remaining recruits can control their aggression, with a brutal game of murderball and the fearsome non-stop 'sickener' exercises

The remaining recruits each face the final, notoriously gruelling stage of selection alone: 24 hours of interrogation. Do any of them have what it takes to succeed in the Special Forces?

The directing staff have to whittle the group down to the six they think may have what it takes to complete the final stage: a punishing 72-hour cat-and-mouse chase across challenging terrain.

The directing staff test the remaining recruits' resistance to fear, with mind games and an intimidating challenge to dive backwards from a cliff into the freezing sea 12 metres below.

The remaining recruits must choose their weakest colleagues, who then lead the next exercise. And there's the 'Sickener': a series of physical challenges that won't end until five recruits give up.
