Lupin the Third: Castle of Cagliostro

A dashing thief, his gang of desperadoes and an intrepid policeman struggle to free a princess from an evil count's clutches, and learn the hidden secret to a fabulous treasure that she holds part of a key to.
After a successful robbery leaves famed thief Lupin the Third and his partner Jigen with nothing but a large amount of expertly crafted counterfeit bills, he decides to track down the forgers responsible—and steal any other treasures he may find in the Castle of Cagliostro, including the 'damsel in distress' he finds imprisoned there.
