Tennis great Roger Federer joins Bear on a grand slam journey through the Swiss Alps. After meeting up amidst stunning snow-capped peaks, Bear and Roger descend a frozen waterfall and use tennis rackets as snowshoes to cross a frozen lake. After a quick snack of fish eyeballs, the pair get creative with a tennis ball to ascend a steep cliff that is their only way home. Along the way, Roger discusses the hard work it takes to achieve victory, his amusing experiences raising two sets of twins, and takes on the challenge when Bear invites him to a hilarious match of ping pong.

Dropped amidst snow-capped mountains, Uzo and Bear move quickly as a storm sets in, sending hail, lightning and flash floods their way. Along the way they come face-to-face with a poisonous viper, get creative to secure a dinner of field mice, and use a crossbow to zip-line across a 250 ft. drop. Despite the elements, Uzo shines as she recounts her long road to fame, her family's emigration from Nigeria, and her pride in representing the American dream.

Captain Marvel herself, Brie Larson, accompanies Bear on a jungle adventure across a remote island in the Gulf of Panama. A 48-hour getaway from Hollywood is what this Oscar winner needs,but there's no such thing as a relaxing vacation with Bear Grylls! They begin their journey by jumping out of a helicopter into the ocean. From there, they make a perilous trek through a crocodile-filled mangrove swamp that turns into a dangerous maze as the tide rises. It'll take Bear's bushcraft skills and Brie's super powers to complete this adventure!
