Hearts and Armour (1983)

Bradamante, a woman wearing an invincible suit of armor, is travelling the countryside at the time of the Crusades. After ending up in the middle of a web of romantic and cultural tangles, she finds herself in love with a Moor prince, while one of the Christian knights has fallen in love with a Moor princess. Others, however, are against the cross-cultural romance, and Bradamante's love is soon forced into a duel to the death. Will she ever be with her true love?
