MrBeast hosts a high-stakes competition featuring 30 celebrities, including Kevin Hart, Paris Hilton, and Howie Mandel, battling through a series of physical, mental, and culinary challenges for a $1 million prize to be donated to their chosen charity. Challenges range from a car giveaway dodgeball game to a memory puzzle, pole endurance, and a team cooking competition judged by celebrity chefs. The final three contestants navigate elimination cubes and a briefcase selection game, culminating in Steve-O winning the million dollars for Doctors Without Borders, with additional donations to the other finalists' charities, all while promoting MrBeast's 'Beast Games Season 2'.
