Ten survival specialists from Mexico, Colombia and Argentina are divided into five pairs and are abandoned naked in the inhospitable Colombian savanna. There they must survive the next 21 days at the mercy of nature.

The five pairs realize that the challenge is more difficult than they expected. Your main objectives: Obtain drinking water and food and build shelter, will be obstructed by an unexpected enemy.

Colombia's climate continues to give survivors no respite. Enduring extreme changes in temperature becomes a mental and physical challenge for most couples. Some are already contemplating the possibility of abandoning the challenge.

The harshness of the climate, thirst, hunger and fatigue affect the relationships between most survival experts. Everyone's emotions become difficult to manage. Defections begin in some pairs.

After a week at the mercy of nature, the couples have realized how intense this experience is. The desire to cover basic needs and the scarcity of resources in the area become a time bomb.

The survivors enter the final stretch of the challenge and face new problems and conflicts. 2 participants must show what they are made of by being left alone in the challenge.
