A millenary language agonizes: Its last two speakers, Evaristo and Isauro (70´s) had a quarrel 50 years ago and haven't spoken to each other since. Martin, a linguist, will undertake the challenge of bringing the two old friends back together and convince them to talk again in order for him to be able to obtain a record of the language. Yet, hidden in the past, in the core of the jungle, lies a secret hidden in the language that makes it difficult to believe that the heart of Zikril will beat again.

Bitter, grumpy patriarch Don Servando and his family travel to spend Christmas with Doña Alicia, a relative who becomes his "ultimate nemesis". It may be Christmas, but Don Servando is set on proving to everyone that Doña Alicia is a terrible person.
