Clementine is a genius. She can calculate pi to 69,689 places, remembers the exact moment she was born, and dreams in Latin. She's also a mouse. And when she escapes from the lab which has bred her, Clementine discovers that it's not enough to be the smartest mouse in history if she wants to survive in the real world - especially while the scientists who kept her are trying to recover their prize specimen. So, together with her new human friends, Clementine must find a way to earn her freedom - for good.
