The Devil's Mirror (1972)

The Jiuxian Witch and her Bloody Ghouls Clan (somehow you just know that these aren’t the good guys) are planning domination of the Martial Arts world. Standing in their way are two clans who posses a magic mirror each. The two clans enjoy friendly relations, but when one mirror is stolen and the blame seems to rest with the other Clan, suspicions and tempers run high. It’s left to the young renegades from each Clan to find the true culprit or culprits, and to ease the tensions of their families. Not to mention ridding the world of the evil Jiuxian Witch.
