Smile! It's picture day! Except maybe don't smile, because there's a glowing lost-and-found box that's appeared in the cafeteria. Sure, coming to Strangeville Middle has been an adjustment for new kid Harvey Hill, but things seem to be going well. That is, until strange things happen that may or may not be related to a 50-year-old curse (if, of course, curses were real, which they definitely are not).

Luckily Harvey and his friend Stella are on the case. Their classmate Nevaeh seems to think there's a logical explanation to the sentient robots, flooding hallways, and the glowing lost-and-found box, but Harvey and Stella aren't convinced. Is Harvey brave enough to solve the mystery of the curse (ahem, if there is one)? Or is Strangeville doomed?
