In search of a better life, a kind rat with inquisitive beady eyes one day sets out in search of a loving home where he will be accepted for who he is. In the park, he meets a girl named Sasha, who invites him to live with her and gives him a name - Mr Rat.

Mr Rat and little Sasha will have many adventures: together they will help their dad paint the walls and bake cupcakes for their mum. Mr Rat will also meet some amazing creatures: Lightning the bat, who lives in the bakery, and an old owl who lives in the hollow of a perennial oak tree. Mr Rat will rescue the wild cat Coal and fly in balloons. And wherever he goes and whatever he invents, his best friend, a little girl named Sasha, is always with him.
