The new final four teams now travel to the Bahamas where they first must find a secret map that leads to an underwater treasure. Josee's claustrophobia makes her run out of oxygen really fast but MacArthur reluctantly rescues her. Meanwhile, Sisters Emma & Kitty are delayed when Kitty gets stuck in a rock. Geoff & Brody came in first despite returning to the race. Once the rest of the teams escaped, it's a close race to the finish. In the end, Emma & Kitty end up coming in last so they are the last team eliminated from the race. The new final 3 teams now make their way to the finale in New York City.
