The Straw Hat Pirates meet the evil pirate Shiki. When Nami can warn him about an oncoming storm nobody else sees, he decides that he has to have her as a navigator. So he kidnaps her and leaves the rest of the crew stranded on a few floating islands that boast the weirdest – and most aggressive – wildlife.
I have never watched or read One Piece before, and I have to say that this movie did not make me want to watch it. It was perfectly fine, even though a little ridiculous, and I had no problems following it, though I knew nothing about the show*, but it just didn’t float my boat.
