Bob Parr used to be Mr. Incredible, one of the world's greatest superheroes, saving lives and fighting evil on a daily basis. But 15 years later, due to a series of expensive lawsuits and some really bad press coverage, Bob and his wife (a famous former superhero herself) have adopted civilian identities and retreated to the suburbs with their 3 kids. Now Bob is a clock-punching insurance claims adjuster fighting boredom and a bulging waistline.
Itching to get back into action, Bob gets his chance when a mysterious communication summons him to a remote island for a top-secret assignment. It leads to the discovery of a plot to rid the world of all superheroes - a plot hatched by someone from Bob's past.
