PREVIEW: Celebrity SAS: Who Dares Wins (S3), Channel 4

Twelve celebrities head into the wilds of the Scottish Hebrides.

Chief Instructor Ant Middleton and his team of Directing Staff (DS) apply pressure through a series of gruelling tasks and interrogations that will test the recruits both physically and mentally. Do these celebrities have what it takes to pass SAS selection?

In this episode, the recruits tackle the 'trainasium' - an aerial assault course designed to test how candidates manage fear. As the recruits get to know each other and relationships form, some of them are already feeling the pressure of the course.

TV presenter Ulrika Jonsson and TV personality Kerry Katona must face their demons and delve into their pasts. For the final task in this phase the recruits must attempt to rescue a hostage from a building that has been exposed to CS gas.

Celebrity SAS: Who Dares Wins returns Sunday 29th August at 9pm on Channel 4.
