Four kids are enlisted by mysterious Mr. Benedict to go undercover at a strange school in order to prevent the world from being controlled by a sinister man. Reynie Richards is a natural leader and excellent at putting together clues and solving mysteries. Sticky (George) Washington has photographic memory and a seemingly infinite amount of knowledge in his head. Kate Wetherall may not be a genius, but she is always prepared with her supply-stocked red bucket, and her surprising agility and strength. And while it may seem like Constance Contraire's only talents are stubbornness, grumpiness, and the ability to come up with insulting poems, Mr. Benedict is certain that Constance is a vital team member as well. So the four unusual children pack their bags and start their dangerous, and possibly deadly, undercover mission, knowing that they may be the world's last hope.
And just like that, the Mysterious Benedict Society is born.
