When someone kidnaps the beloved school mascot, Eddie the Owl, Moxie is on the case - but she is forced to fly solo since her best friend (and crime-solving partner) has recently moved away. Moxie must interview her classmates - both as potential new best friends, and as possible suspects. She finds clues and points fingers but can't save the owl on her own. Enter Moxie's little brother, Milton. Quiet and cautious, he listens carefully and helps connects the dots. Can the Real McCoys form an unlikely alliance and solve the crime of the century? The Real McCoys delivers clever storytelling and heartwarming insight in an irresistible package.
