Isidoro is a lazy guy, who loves parties and casinos, but has never worked, so he lives off his father's inheritance and making his uncle suffer. But because his uncle, Colonel Cañones, is accused of a crime against the nation, Isidoro must work for the first time in his life to find the true culprit.

Fallas de Origen is a mockumentary about the capacity of the "Argentine being" to pass up any opportunity to prosper, exploring the cause of Argentina's constant failure. Conspiracy theories, secret potions, mass poisonings, magic vaccines, colonialism, and millions of Argentines attacking a country every day. Ministries that change everything so nothing changes, and Argentines deceiving Argentines. A society determined to fail and evade responsibility.
