Vincent, an 11-year-old ordinary boy from a poor family, was invited to work at the Most Extraordinary Hotel in the World! And from that day on, his life began to resemble one huge adventure. What is there in the hotel? Firstly, rooms for every taste. For example, the Laughter Number, the Flying Number, the Childhood Memories Number... But the most important thing: Vincent found a friend at the hotel - a girl named Florence. She runs the hotel while her parents are busy collecting material for a gene bank for endangered species for the third year in a row. But everything changes when Vincent decides to look into the Room with Mirrors of the Future (even though this is strictly prohibited!). And now he needs to think about how to save Florence, his only friend, from a terrible prediction!
