What a squirrely mess! After the flying squirrel Henry terribly fails in the master thief examination, the entire city of Chicago is laughing about him. He hastily leaves the country. His destination: Castle Sparklestone. There is supposed to be a huge diamond hidden there, and nobody has been able to find it as of yet. If Henry manages to steal it, his reputation will be restored for good!
Masked as the superhero Mouseman, he turns up at the castle and quickly makes friends with the animal inhabitants. There is kitchen mouse Miffy, Liesel the curious little weasel, and the charming hazel dormouse girl Adelina, of course. But what will they think of him when they find out that he is a thief? For his new friends, Henry has to take a decision: be a hero or a scoundrel?
