Leo

Jaded 74-year-old reptile Leo has been stuck in the same Florida classroom for decades with his terrarium-mate turtle. When he learns he only has one year left to live, he plans to escape to experience life on the outside but instead gets caught up in the problems of his anxious students — including an impossibly mean substitute teacher.
