Rappelling from a helicopter, Bear takes Florence Pugh to the volcanic rainforests of Costa Rica. Bear shows Florence how to traverse rapids, test river depth with a rope and rock, and avoid poisonous snakes and deep cliff edges. Crossing an alligator-infested swamp, they catch eel for dinner. On day two, Florence must test the depth of a waterfall pool before choosing to leap from a high cliff into a set of rapids below. Finally, they jump out of an airplane at 10,000 feet to their extraction.
