100-day challenge where two strangers, Bailey and Susie, are isolated in a white chamber with the promise of $500,000 if they both remain for the full duration. Throughout the challenge, MrBeast offers them various temptations, such as a private chef, comfortable beds, entertainment, and even a chance to see their families, all for a portion of their prize money. Despite facing extreme boredom, frustration with each other, and tempting offers, they ultimately succeed in completing the 100 days. In the final twist, they are given the choice to split the money or steal the other's share, and both choose to split, walking away with their $250,000 each.
