On a small Mexican island dwells a group of Indians who live in the traditional manner and who disdain outsiders. The beautiful Maclovia and the poverty-stricken Jose Maria are in love, but her father refuses to allow their marriage, or even any communication between them, due to Jose Maria's lack of means.
