A lighthouse guardian leads a young prince towards an imaginary world, Taxandria, where the boy learns about the power of love and the value of liberty. A totalitarian regime has forbidden time: time watches have been confiscated, photo cameras are illegal as they freeze a point in time. A typical Servais theme: a power is oppressed by a constraint that denies what is best in the individual, and therefore has to be twisted in various ways, to establish an entirely artificial world, that has rules that may question some of the rules of our world at this side of the mirror.

Un jeune prince, condamné a reviser ses examens dans un palace au bord de la mer sous la ferule de son precepteur, s'ennuie. Il est très attiré par le phare au bout de la plage. N'y tenant plus, il fugue et rencontre Karol, le gardien misanthrope qui soigne les oiseaux blessés trouvés sur la plage. Karol va ouvrir au jeune prince les portes de l'imaginaire et du rêve en lui faisant decouvrir une ville mysterieuse, hors du temps, Taxandria.
