De pracht van het landgoed Moonacre wordt overschaduwd door herinneringen aan de Maanprinses en het mysterieuze witte paardje. Tot haar verrassing ontdekt Maria Merryweather, een vreemdelinge in het Kasteel van Moonacre, dat wat er al die jaren geleden met de Maanprinses gebeurd is, ook met haar te maken heeft. Ze is vastbesloten vrede en geluk terug te brengen in de vallei. En Maria krijgt meestal haar zin.
Nee, helaas is De maanprinses en het geheim van het witte paard nog niet beschikbaar op Netflix in Nederland.
