This is a very special day for the Grand Hotel's team. The Olympic Games of the hotel industry, the Hôteliades, are taking place at the hotel. The best hotels confront one another in this competition that the Concierge would give anything to win. While the Bellboy doesn't want to get involved in the competition, the Housekeeper is falling in love with a referee.

The employees of the Grand Hôtel are more worried than ever that the hotel will close for good. The hotel's owner, the Bellboy's father has decided to transform it in an orphanage. While the Housekeeper leads the resistance and tries to mobilize the hotel's clients, the Bellboy attempts to convince his father to change his mind.
