Morgan Adams' father's dying gifts to her are his pirate ship and a one-third part of a map of a treasure island - unusually inscribed on his scalp. Thinking herself in need of a Latin scholar to unravel the map, she buys learned slave William Shaw and sets off in search of the rest of the map. However, it is Shaw, obviously with plans of his own, who gets the second part. He's somewhat easier to deal with, though, than the holder of the last part - Morgan's less-than-loving piratical uncle Dawg.

The flag flown by Morgan Adams was in reality the flag flown by "Calico" Jack Rackham, one of the only Caribbean Pirates to have women on his crew; Anne Bonny and Mary Read. He later turned his ship over to the two women.

Dawg:
You plannin' to fight me with that little stick?


Morgan:
No, Uncle. With this!

[Morgan reveals a loaded cannon and lights it, aiming it at Dawg]


Morgan:
Bad Dawg!

Anachronisms: The Finnish flag on the shop front window was not in use at the time the film was set.
