The Prodigal Son

The great Yuen Biao stars as Leung Jan, a rich man's son who believes himself to be a great kung fu fighter (in reality, his father has been paying his opponents to lose). When he finds out the truth, he leaves to become the student of a powerful martial artist. Unfortunately, this new master has a rival, an evil kung fu master with a posse of ninjas, and he's injured in a brutal battle. Leung Jan flees to the countryside to train under the guidance of a weird kung fu hermit (Sammo Hung), and plan his revenge.
