Naked and Afraid Spain

Five couples of strangers venture 21 days into the Colombia.

In the early stages of the challenge, some do not finish their shelter, find food, or make fire; friction between the couples begins; hunger, thirst and the dangers of the jungle start to take their toll; one participant abandons the adventure.

As the jungle claims its first victim and menace looms over the others, a couple's marriage teeters on the brink of divorce amidst mounting tensions.

After the storm, mosquitoes arrive as a challenge, while hunger sharpens the adventurers' ingenuity.

Exhaustion sets in and some seek shelter until extraction.

Some participants start the exodus towards the extraction point; not everyone reaches the final stage of the challenge.
