The little dog has had enough of sitting in remote offices in front of the TV while his parents have one meeting after another. When they forget him on a business trip in the hotel, he has had enough. He decides to stay at the Grand Hotel Bellvue - his parents can pick him up there later. And so the little dog swaps yawning boredom for an adventurous internship in the hotel business, stirring up a lot of dust in the process. Because the Grand Hotel is anything but ordinary. The staff, from the chambermaid to the hotel manager, is also quirky - but above all, kind-hearted. When his parents pick up the little dog at the hotel days later, they can hardly stop being amazed.
