Ben Fogle takes a team of would-be adventurers on a gruelling jungle trek. There are eight applicants, all of whom want to be challenged physically, mentally and emotionally. Amongst them are a Kent housewife who has dedicated her life to her family and a landscape gardener from Derbyshire who has never spent a day apart from his wife. Ben is aided by naturalist Charlotte Uhlenbroek and psychologist Cynthia McVey.
