Robin and the Golden Arrow

On Prince John's orders, Captain Delouche, an evil knight armed with magic, impenetrable armor, rounds up many young women from the Sherwood Forest area for a beauty contest, with marriage to Delouche for the winner and a sacrificial death for the loser. The abducted women include Little John's sister, Natalie. The magic armor can only be defeated by the Golden Arrow, which Robin has to take from Prince John's castle, and use against Delouche, to rescue the maidens.
