Bear Grylls: Mission Survive begins on ITV tonight as eight celebrities face a 12-day survival mission unlike anything they’ve ever experienced before.

To stay alive they must learn to navigate difficult terrain, build shelter, make fire and eat food that nature provides.

From abseiling down ferocious waterfalls, crossing perilous rapids, trudging through swamps and eating rats and scorpions; this series has it all as the celebs go on an epic adventure in the rainforest of Costa Rica described as 'I'm A Celebrity on Steroids'.

In tonight's opening show the expedition team are transported from their lodgings in a helicopter to a rainforest clearing at the foot of Arenal Volcano.

From here the mission will start; testing their resolve, resilience and spirit.

First they must jump out of the chopper into an algae covered swap where they must swim to the bank and trek through the jungle, all just to meet Bear.

And when they arrive, the stars of the show find that Bear has a surprise for the celebrities – a cow’s heart and brain.

He tells them they will need to have heart and brains to survive the mission. But they will also have to eat both to provide them with additional nutrients to supplement their army ration packs of food.

Other challenges in tonight's opening show include setting up the camp and shelter as well as collecting eggs from high up in trees.

At the end of it all, the celebrities face the first elimination: Which celebrity will be on their way home and who will continue on Mission Survive?

The show starts TONIGHT at 9PM on ITV.
