Ep 3. Last Man Standing

The first days of the challenge have been exhausting for the five pairs of adventurers. Even though they haven't been out there for a week, they are already suffering from fatigue, hunger and overall weariness. On top of the challenges of finding food and potable water, they must deal with venomous snakes, wild animals and ticks -- constant threats they must learn to live with. Rain and storms are also arriving. If they don't manage to find shelter, they'll be in serious trouble. The jungle has already claimed Sara and threatens to take more adventurers.
