Well, it's about a girl whose name is Buttercup, who lived on a small farm in the country of Florin. She falls in love with 'Farm Boy', Westley, who tells her he loves her by saying 'As you wish'. So Westley and Buttercup want to get married, but Westley didn't have enough money, so he goes across the sea to seek his fortune. The Dread Pirate Roberts attacked and he never leaves prisoners alive.
Five years later, the Prince Humperdink announces his bride as... Buttercup! She refuses to marry him and rides alone in the forest, where she is captured by Vicini (a sicilian) Inigo Montoya (Expert swordsman, spainierd) and Fezzik (A giant.) Vicini's going to start a war with the neighboring country of Guilder. "Who's Guilder?' You may ask. "The country across the sea. the sworn enemy of Florin."
I'll leave the rest for some one else to tell, unless no one wants to tell it.
