Blas Jaime, a retired man from Entre Ríos, Argentina, being 71, publicly revealed, that he is the last heir of the Chaná language, an ethnicity native from South America, that was considered extinct for more than 200 years ago.

Together, they embarked in an odyssey to transcend this cultural legacy with the purpose of it not to vanish as most languages around the world. Could they transcend his legacy?
