Overview: Adam, Jen, Kareem, and Zac canoe across a swamp to an abandoned beaver lodge. Catarina returns to the show. Forced to abandon their canoes and with limited supplies (including plastic garbage bags, a magnesium fire-starter, and a teakettle), the five must swim and walk across the swamp to a marshy area, build a shelter on the water, find food and water, and spend the night on the water. Catarina has an emotional breakdown after crossing the swamp; Kareem and Zac try to calm her while Adam and Jen build the sleeping platform on the water. The five walk and swim across the swamp to reach dry land again. Catarina leaves the show once more.
