Unbreakable is a new eight-part, hour-long series presented by one of Britain’s leading adventurers, Benedict Allen. The series takes ten intrepid volunteers on a gruelling global trail that sees them undergo a series of demanding challenges. These include: intensive training with the Navy Seals; surviving the Guyanan Jungle; braving the Norwegian Arctic and enduring extreme military exercises with the South African Special Forces.

They will have to withstand some of the world’s toughest military selection tasks and learn to survive in the world’s harshest environments. Along the way they will grapple gators in the swamp, wrestle anacondas in the jungle, dive through ice holes into arctic water, be buried up to their necks in the African desert, fight off ‘the bends’ in 100 feet of water, battle to save a sinking ship and endure in an Afrikaans trial with the South African Special Forces. They will be beasted and bossed by physical trainers and survival experts as they bid to outdo and outlast each other.
