One night, young Tom is awoken by noises outside his house. He peeps out of the window and what should he see but PIRATES. And stranger still — they're GIRL PIRATES stealing the front of his house! Tom joins their pirate adventure across the high seas to an island where some rather lazy and silly grown-up pirates are guarding their treasure. But not very successfully. Tom and the girl-pirates make a surprise attack and are soon off on the seas once more with the treasure!
