Martin arrives in a remote Mexican village to record a dying, ancient indigenous language. He finds the last two speakers of the language, but they refuse to speak to each other because of a 50 year grudge. Martin learns the surly Evaristo got into a fight with Isauro because they fell in love with the same woman. Now widowed, Evaristo continues to bitterly avoid the ailing Isauro. Martin and Evaristo’s granddaughter, Lluvia, work to convince the men to reconcile. Perplexed by their intensity when they meet, Martin realizes there is more to the story, and Lluvia finally reveals the secret behind the men’s entanglement. As Isauro’s health declines, Evaristo struggles to come to terms with his feelings, and strange bird calls from deep inside the jungle begin to stir, evoking the mythical origin of their ancestors.
