A young man returns home to a mother from whom he ran away as a child. Since she doesn't know what he looks like, a fugitive sees the opportunity of impersonating him and tries to kill him. The heir survives but loses his memory. Following only his instinct, he keeps moving and somehow reaches his native village where the villain is now living under a fake identity. Having lost his memory, the real heir is nothing more than a madman and even his mother fails to recognize him. The only person who may have a hunch about the heir;s identity is a blind, old female fakir.
