A Double-Dyed Deceiver(1920)

Most of the scenes are laid in a parrot-and-monkey country in South America, a land where "it is always after dinner." The Llano Kid, a Texas bad man, flees there from justice. The consul persuades him to play the long-lost son of a Castilian family, and tattoos a coat of arms on the back of the Kid's hand to make the deception complete. The Kid is taken into the household, trusted and loved by the gladdened mother. For the first time he has a home. The romance develops. And when the time comes to rob and flee he has too much manhood to break the loving mother's heart. The surprise comes when it is revealed that the man the Kid killed in Texas was the real son.
