In the Spain of the early 19th century there is no place for everyone, much less for traitors. A woman nicknamed La Llanera is released from prison after 17 years. During her imprisonment, she has been sentenced every year to the gallows and pardoned at the last moment. Her son Juan de Ella was born in the cell and does not know her father, the famous bandit Lagartijo. Mother and son will try to live the freedom that has been denied them for so many years while they are persecuted by gangs of bandits and gunmen from the Governor. Lagartijo, Aceituno and the Governor look for La Llanera, but they also look for each other.
