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 adventure across the high seas to an island where some rather lazy and silly grown-up pirates are guarding their treasure. Not very successfully! Tom and the girl-pirates make a surprise attack and are soon off on the seas once more with the treasure!
