The Fantastic Family follows the adventures of a family (almost) like any other, catapulted into a world as fascinating as it is dangerous.

It's vacation time and Charles and his blended family have decided to go spend it in their country house. But they have an unexpected encounter along the way with a young boy dressed as a medieval prince pursued by a huge monster. They soon discover that they were somehow diverted to Fantastica, an imaginary world worthy of the best fantasy novels, plagued by wars and power games.
Little do they know what's waiting for them there...
