Imp is a junior demon who causes mischief in human homes. When he gets left behind in a little girl's room he faces the most difficult choice of all - will he decide to be good or bad?

As a junior demon, Imp's job is to cause mischief in human homes.

But when his antics lead to him getting left behind in a little girl's bedroom, Imp realises that there might be more to life than getting up to no good.

In an attempt to find his way back to the demon world, he follows Margot around, joining in with her daily activities. But the more time he spends with her, the more he enjoys being good and helping her.

Unfortunately for Imp though, walking away from his old life is not easy, and when Lucifer, the king of the demons, finds out what Imp has been doing, he threatens to destroy the human world for good.

Will Imp and his friends be able to stop him, before it's too late?
