Love is in the air in the wake of the first dramatic Plank Ceremony, but choppy waters are in the forecast. The Chakra is flipped upside down when Gabby introduces the first challenge, resulting in new Topside couples, new Downside crew and one scary close-call. Happy Hour sees connections deepen and new love triangles form as the Downsiders seize their opportunity to make it to the Topside. Sofia puts a scheme in motion to change her fate by pulling a fast one on an unsuspecting Topsider. But the walls are thin on the Chakra, and word of Sofia's plan quickly spreads. The result is the most dramatic Plank yet.
