Captain Glenn is back on board Parsifal III, sailing the Balearic Island of Menorca with some familiar faces -- Daisy, Gary, and Colin; new to the team, Chef Marcos knows he has to make this season memorable for the guests.

Parsifal III's new crew figures out how to work together to execute a successful first charter. Marcos works tirelessly to satiate the massive appetites of the charter guests. Gabriela aims to prove she deserves the second stew title while Ashley works her own angle to convince Daisy she’s the better pick. A sail that is sold to Daisy as mild ends up including a dramatic heel, which leaves glasses broken and her fuming. To make up for the embarrassment of the first night, Tom tries to prove to his new team that he is good at his job but he struggles along the way. The first crew night out leads to conflict between Tom and Ashley after Ashley dismisses Tom’s advances because of his age.

After a wild night off, a hungover Parsifal III crew puts the pieces of the night back together as they prepare for the second charter of the season.

Tom finds it increasingly difficult to find his footing on deck and with Ashley.

Meanwhile, Captain Glenn confronts the primary about a costly damage to the yacht before the charter guests make a swift departure and leave behind a shocking tip. After another boozy hot tub night, Parsifal III’s resident playboy Gary ends his night in an unexpected and steamy way.

While the sexual chemistry heats up on the boat, Ashley and Gabriela continue to be icy towards one another. From the galley, Marcos takes note of the competition unfolding between the junior stews and alerts Daisy, making for an unhappy chief stew. On deck, all seems to be going well, until Tom gets some devastating news from home. His distraction has a ripple effect, resulting in the most perilous situation Parsifal III has ever found itself in.

In the galley, Gabriela and Marcos have a miscommunication during dinner service that causes tension to bubble up between them. Friction between Gary and Daisy intensifies after Kelsie is caught covering Gabriela’s duties on the final day of charter.

The conflict between Gary and Daisy further escalates following their disagreement about their departments. Between the massive new fenders and being a man down, it takes the whole crew to manage a chaotic docking. Ashley finds herself in both physical and emotional pain after witnessing Gabriela and Gary in bed together, but she isn’t the only one frustrated with the second stew. After a tense dinner, Gabriela’s relationships with her fellow crew members spiral out of control leaving her questioning whether or not she can continue the season. With a new charter comes new problems when an exhausted Gary is injured while trying to manage all the exterior duties without a second deckhand.

Tensions rise on the boat for both the interior and deck crew. Gary’s finger gets stuck in the main saloon doors causing so much pain that his patience with Kelsie is obsolete. Still one man down, Kelsie tries to keep her head above water with the new 12-hour graveyard shift. On the interior, Gabriela works hard to amend her relationship with the crew but feels isolated from the team. Ashley confides in Daisy about Gabriela’s attitude, forcing Daisy to have a private conversation with Gabriela.

After getting vulnerable with Daisy about how low she’s been feeling aboard Parsifal III, Gabriela wants to try to turn things around on the upcoming crew day off. Coming off another successful charter and in true celebratory fashion, Ashley goes full steam ahead in her pursuit for Gary. The next morning, however, a hungover Gary claims he can’t remember what happened. The crew head to a luxury villa to unwind, reset and figure out what really happened between Gary and Ashley.
