Return of the 5 Deadly Venoms
1981
After the death of his wife, warlord Dao Tian-du (Kuan Tai Chen) turns evil and holds a town in thrall to his reign of fear with the help of his sadistic son. Four of the villain's crippled victims -- a blind man, an amputee, a deaf-mute and an insane fighter-- seek the help of a wise kung fu master as they train to eliminate the tyrant for good. Despite the title, this film is not a sequel to "The Five Deadly Venoms." Wikipedia
