The bride from Britanny

Medieval Drama set in 13th Century France about a young herald tasked to find a bride for the heir of the duke of Bretagne. But when he's sent to the duke's friend's castle to talk about their daughter as a potential marriage candidate, all he finds is a wild and talented knight fighting in a tournament. To his surprise this skilled knight turns out to be the daughter in question - looking like a young man - and moreover, she wants nothing more but to kill the Duke of Bretagne in revenge for her father's murder.
