Showbiz at sea! In a special episode, Sea City follows a cast of new recruits to the Academy, where young performers on P&O cruise ships learn and rehearse their shows. With a gruelling eight-week schedule before they join the Aurora on a round the world cruise, the singers and dancers must get their stagecraft up to scratch and impress creative director Stevie Bee. Sea City then joins them on their cast debut on board Aurora, as they fight sea sickness and first night nerves. Will they win over their first audience of passengers?
