Video game bad guy Ralph and fellow misfit Vanellope von Schweetz must risk it all by traveling to the World Wide Web in search of a replacement part to save Vanellope's video game, "Sugar Rush." In way over their heads, Ralph and Vanellope rely on the citizens of the internet -- the netizens -- to help navigate their way, including an entrepreneur named Yesss, who is the head algorithm and the heart and soul of trend-making site BuzzzTube.
Wreck-It Ralph is the 9-foot-tall, 643-pound villain of an arcade video game named Fix-It Felix Jr., in which the game's titular hero fixes buildings that Ralph destroys. Wanting to prove he can be a good guy and not just a villain, Ralph escapes his game and lands in Hero's Duty, a first-person shooter where he helps the game's hero battle against alien invaders. He later enters Sugar Rush, a kart racing game set on tracks made of candies, cookies and other sweets. There, Ralph meets Vanellope von Schweetz who has learned that her game is faced with a dire threat that could affect the entire arcade, and one that Ralph may have inadvertently started.
