Against all odds, Luffy and his Straw Hat crew make landfall on Water Seven, a wacky maritime wonderland where the world's best (and worst) shipwrights gather. When the pirates learn that their trusty vessel, the "Merry Go, " has sustained irreparable damage, the decision about what to do next rends the crew apart! In the meantime, mysterious archaeologist Nico Robin's dark past as a double agent is catching up with her, and the Franky family, a nasty clan of ship-scrapping bounty hunters, seem bent on the Straw Hats' destruction!
