The video features Lizzie and her guests competing in a challenge called "Last Person to Leave the Pool Wins $10,000." The rules are simple: a circle around the perimeter of the pool will shrink every 10 minutes, and the last person to leave the pool wins the grand prize. The contestants must stay within the designated area, which gets smaller as the challenge progresses. If someone leaves the area, they are out of the competition.
Throughout the challenge, contestants are eliminated through various methods, including a plank-walking challenge. In the end, it comes down to Lizzie and Kelsey, who compete in a final challenge to push a pair of Crocs across the pool using a pool noodle. Kelsey emerges as the winner, taking home the $10,000 grand prize.
