After a brief stop in Madeira, Captain Victor Stoica soon has a medical emergency on his hands as a sick passenger has to be airlifted off the ship in the middle of the Atlantic. On board, Colin and the passengers settle into a routine. Sue Alderson, the energetic choir mistress, is soon drilling her passenger volunteers for a performance of The Pirates of Penzance at the end of the leg in Acapulco. Bob and Vivien Spedding met and fell in love on a previous cruise, but are on a honeymoon with a difference this time.
