Perekond Salmonid on Eestit valitsenud viimased veerand sajandit, nii kaudselt kui otseselt. Rikkusest on saanud jõukus ja saavutustest võim. Perepea Ella Salmon (Ita Ever) on olnud isegi president! Kuid sellestki jääb väheks.
Join Lotte and her uncle Klaus as the two of them set off on another funny and charming animated adventure, this time in Lotte and the Moonstone Secret. In their last adventure, Klaus and his friends Fred and Ville took three stones from a secret temple.
