1470. The Canary Islands try to resist the Spanish invaders. Their inhabitants are divided, their chief and his daughter Guayarmina (for whom a Spanish officer has fallen in love) wanting the peace, while the priest and resistance leader are for war. After several battles the islanders are chased to Tirma mountain by the Spanish army.
Unfortunately the movie The Island Princess is not yet available on HBO Max.
