World heavyweight champion Anthony Joshua steps outside the ring and his comfort zone as he attempts to survive two days in the wild with Bear Grylls. Anthony starts his journey dangling below a helicopter, as Bear whisks him off to the notorious Commando Ridge in Cornwall - one of the UK's most famous climbing faces and where the Royal Marines have trained since the Second World War. Anthony must traverse a 100ft rope 200ft above the sea, using only his balance and strength. Later, he has to face a 200ft abseil on his own. As the adventure nears its end, Bear lights a flare to attract a boat to collect them - but they will have to swim out to sea to meet it. Does the heavyweight champ have what it takes to go the distance and complete his mission with Bear?
