Leah and Finley are starting high school in the fall so it's their last chance to totally goof off as kids. They make a list of ten things they've always wanted to do and secretly try to complete them all, from building a throne and driving a car to finding buried treasure and attempting a world record.

They're set to have an amazing time but mental health struggles, growing responsibilities and self-esteem issues aren't as easy to ignore now that they're teenagers. This summer they'll need to fight for their friendship and for their childhood dreams to last a little longer.
