In 1916, the notorious bandit El Guapo (Alfonso Arau) and his gang of thugs are collecting protection money from the small Mexican village of Santo Poco. Carmen (Patrice Martinez), daughter of the village leader, searches for someone who can come to the rescue of her townspeople. While visiting a small village church, she remains to watch a silent film featuring "The Three Amigos" and, believing them to be real heroes, sends a telegram to Hollywood asking them to come and stop El Guapo. However, the telegraph operator edits her message down since she has very little money to pay for it.
