[ EU ] Write me the plot to The Incredibles 2

It's 20 years later, and the Incredibles have fallen out of the crime-fighting business, adapting to regular life except for Jack-Jack, who is now the world's most well known hero. When he is captured by a rogue group of Underminers- furious that they never got their own chance to be movie villains- the family must reunite, risking everything in order to save him; enlisting help from old friends as well as some of their greatest enemies. The fate of the world once again hinges on the greatest family that ever lived... and whether or not Frozone can find his super suit.
