Ola's whole family are afraid of mice, and they always have been. Ola doesn't know why, though, so he decides that it's up to him to find out. After questioning each of his family members, he realises that none of them have ever had a bad experience with a mouse, but their fear has been passed down through generations. Ola decides that he needs to decide for himself whether mice are something to fear, so he befriends Roy, a mouse who had previously scared Ola's family. Ola's family are shocked and frightened at first, but soon realise that challenging preconceived notions can sometimes be a good thing
