Even in a school full of monsters, Molly still feels out of place. No matter what she tries to do her 'sister' snakes are always getting in her way. Mischievous and uncontrollable, they scare away her friends and make everything she does so much more difficult.

Molly wants to be in the school talent show, playing her ukulele and winning first prize, but her snakes have other ideas. With help from her friends and a little trial-and-error, Molly finally finds a way to work with her snakes and realises that, although they annoy her, they are her family and she loves them.
