We have incredible stories with people who survived unimaginable situations. We meet NATHAN and KIM MAKER, who got separated from their group on a scuba diving trip and were stranded for 40 hours off the coast of Texas. Then, LOGAN MOORE was on "the trip of a lifetime" hiking in Switzerland when he fell 50 feet into a mountain crevice. RILEIGH DECKER tells the story of surviving an attack from a giant bull shark in the Bahamas, and ANTHONY GRIGSBY and RACHEL VILLARREAL's vacation in Mexico turned into a nightmare when they ingested drinks that were tainted.

Stars of the hit Nat Geo show "Critter Fixers: Country Vets," DOCS VERNARD HODGES and TERRENCE FERGUSON are back with more creatures! Dog rescue owner SUSANA BURGESS provides an update for the Tam Fam, and ALEXIS DEVINE and her viral talking sheepadoodle, BUNNY, are back with us. We have an update from ABBY JARDINE and her popular pet pigeon, PIDGE, and JILL NAKANO and CARSON the surfing dog. And we check in with CITY RANCH, a nonprofit dedicated to providing accessible and affordable horseback riding.
