The Incredibles family takes on a new mission which involves a change in family roles: Bob Parr (Mr. Incredible) must manage the house while his wife Helen (Elastigirl) goes out to save the world.

Edna babysits Jack-Jack, who uses his powers.

The Parrs' baby Jack-Jack is thought to be normal, not having any super-powers like his parents or siblings. But when an outsider is hired to watch him, Jack-Jack shows his true potential.

While trying to leave a quiet suburban life, a family of undercover superheroes are forced into action to save the world.
