Assault of the Final Rival (1978)

Like the legend of Samson, Tao gains his strength from his long tresses, and it is his strength, combined together with the skills taught by an old monk, that has enabled Tao to defeat many well known knights. Jealous at this success, one man seeks to destroy him. He sends a girl to seduce Tao, shear his locks during his sleep, and murder him.
