Ten survival specialists from Mexico, Colombia and Argentina are divided into pairs and are abandoned naked in the inhospitable Colombian savanna.

The five pairs realize that the challenge is more difficult than they expected. They must obtain drinking water and food and build shelter.

Enduring extreme changes in temperature becomes a mental and physical challenge for most couples.

After a week at the mercy of nature, the couples have realized how intense this experience is.

The survivors enter the final stretch of the challenge and face new problems and conflicts.
