In 2014, Channel 5 sent 20 people back to the Stone Age to take part in a social experiment, 10,000 BC.
But things didn’t go as planned.
The ground breaking social experiment based reality show features twenty modern day Brits who leave the 21st Century to go back to the Stone Age.
They include pretty much everyone from all walks of life: There are young singles, married couples and even a whole family of five.
Ranging in ages from 20 to 65, some have enjoyed a rich and privileged life while others have had to work hard for little reward.
Coming together for Channel 5's 10,000 BC, their mission is simply to survive two months in the wilderness by hunting and foraging for food.
As they come face to face with hunger, sickness and extreme weather, this series gives a unique insight into the origins of our human existence and explores what it takes to survive the Stone Age.
But out of the twenty who started, who will make it to the end?
10,000BC starts on Channel 5 next Monday, February 2 and will air twice a week for 5 weeks.
In the opening show, the tribe is dropped into a forested wilderness in a remote area of Bulgaria.
They're housed in a basic Mesolithic style camp supplied with some basic tools, rations and a pile of flint.
Klint, an archaeologist and survival expert, helps the group for their first day but he then departs to leave the contestants to fend for themselves for the next eight weeks.
Will it turn into sing songs around the camp fire or a stone age Hunger Games?
10,000 BC airs Mondays and Tuesdays on Channel 5 from February 2 at 10PM.
