Twelve-year-olds Ivy and Stuart are best friends, but they're also cousins who come from different backgrounds. The cousins are living under the same roof in Portland when Stuart's mom is deployed overseas and his dad decides to move in with his brother and his family, which includes confident, socially active Ivy and her younger, very curious brother, Leaf. Now that he's in a new city, Stuart embarks on adventures with Ivy, and they learn that they don't always see eye-to-eye and that they are better when they work as a team.
