When Suki digs up an old bone tool covered with markings, Molly, Tooey, and Oscar discover the playful pooch has made an important archeological discovery. Now everything the kids find by the river could be an ancient artifact, including a round, washer-like object Oscar tied to a kite and got stuck in a tree. Inspired by Benny Benson, the real-life Alaska Native boy who designed the state flag of Alaska, Molly announces a contest to design an original flag for the Denali Trading Post. As the submissions stream in, Molly finds her hands full of designs, expectations, and worries. Which flag will she choose? The winner proves to be the most unlikely candidate.
