Plot Synopsis

Set against the stunning backdrop of the tropical Whitsunday Islands and world-famous Great Barrier Reef in northeastern Australia, the Peacock Original series BELOW DECK DOWN UNDER explores the complex, often explosive dynamics of the crew and a rotating group of demanding charter guests on M/Y Thalassa. In the first season, Captain Jason Chambers is joined by a familiar face, fan-favorite Aesha Scott as Chief Stew, along with newcomers Chef Ryan McKeown and Bosun Jamie Sayed. Stews Tumi Mhlongo and Magda Ziomek are also on board with deckhands Culver Bradbury, Brittini Burton, and Benny Crawley. Setting the tone for the entire crew, the youthful, charming new captain has a hands-on leadership approach and will do whatever it takes to make sure the guests have an unforgettable vacation, including mesmerizing under-water excursions like scuba diving, snorkeling, and some close encounters with marine life. Though the dynamics on board are initially smooth sailing, a boatload of problems bubble up when the Chef immediately falls out of sync with the Chief Stew. The deck team also hits rocky waters when the Bosun's firm management style is called into question by a free-spirited team member with an aversion to rules. Meanwhile on the interior, Chief Stew Aesha learns the hard way that not everyone on her team will be motivated by her friend-first work mentality. Between charters, the yachties blow off steam by taking full advantage of Australia's world-renowned nightlife, where drama, surprising flirtations, and wild adventures heat up their well-deserved nights off.

Now a more seasoned leader, Aesha takes on some of the biggest obstacles of her career while looking out for the crew's well-being. Mouth-watering menus and flavorful spreads delight the guests, but frustrations simmer between Chef Tzarina and Jason when he assists in the galley. Initially understaffed, the deckhands make costly errors as they struggle to find their stride on the unpredictable, aging vessel. The interior experiences smooth sailing until a clash of work styles creates a rift between the stews.

Jason is at the forefront of Motor Yacht Katina, the franchise's largest vessel yet. With clashing department heads and hard-to-entertain guests, he must explore new depths to face this season's challenges.

However, a weevil infestation and rising tension with her sous chef threaten to turn her kitchen into chaos. New Chief Stew Lara excels at keeping her department in tip-top shape, going to great lengths to make sure her guests have a spotless experience - even if it means scaling four flights of stairs for every service.
