"Below Deck Mediterranean" cruises to the crystal-clear waters of the Dalmatian Coast of Croatia. The crew boards the 180-foot mega yacht "Lady Michelle" and embarks on an exciting new charter season as they head to Šibenik, the oldest native Croatian town on the shores of the Adriatic Sea. Personalities clash and tension quickly escalates as a crew member's grudges start to rock the boat and disrupt the workflow. In a shocking franchise first, a serious crisis occurs before the opening charter, leaving the staff to worry if the season will be over before it even begins. While unprecedented permutations in the crew structure disrupt the dynamic of the boat, one department head's new management style causes friction that spans to the entire crew. Amidst roommate issues and health scares, the staff encounters one demanding charter group after another, all while continuing to provide the seven-star service that is expected in the Med. Between charters, long workdays lead to late night hijinks, surprising hook-ups and one heated, over-the-top argument in the hot tub that leaves the group at a crossroads.
