Wreck It Ralph is about an arcade game villain who is tired of being the bad guy and just wants to have friends and spend his life with other people, instead of living alone in a garbage yard. In his quest to try to prove that he can be a good guy he wants to attain a medal for proof. This leads him to visit several other games in search of a medal and then when lost in an unlikely girly racing game (Sugar Rush) he loses the medal. In it's loss he makes an unlikely friend with a character who is a glitch in her game. In the end they must team up to save their games from being unplugged and protect the other games from being over-run by something that could destroy every arcade game plugged in.
