Episode 4: African Monsoon
Terrible weather conditions turn the expedition into a struggle for survival. As the explorers begin the day’s hike, they realize the rainy season is closing in on them more quickly than they thought. Their progress is hampered by heavy downpours, and the group begins to fear hypothermia as they are forced to slog through mud and rain. When serious illness hits one member of the expedition, the explorers begin to wonder if they will ever get out of Sagara.
