PARK CITY, UTAH Jan. 27 (UPI) -- Cookie Queens, which premiered Sunday at the Sundance Film Festival, is an irresistibly adorable documentary about Girl Scout cookies. Executive produced by Harry and Meghan, Duke and Duchess of Sussex, the film celebrates childhood sincerity.

Director Alyssa Nahmias follows four Girl Scouts and their families during the six week Girl Scout cookie season. Olive is 12 and keeps besting her own sales record.

Nikki, 9, is the third sister in a family of Girl Scouts to join. Shannon Elizabeth, 8, is trying to sell enough to go to Cookie Camp. At 5, Ara is the youngest and newest, just a Brownie, only trying to sell 55 boxes.

The families first decide on how much inventory to order. Ara's family only has one stack of boxes, but the other three families' stashes look like warehouses.

This also puts families in a bind. Olive's knows their daughter will move product, but Shannon Elizabeth's family can't afford to pay Girl Scouts for $2700 worth of cookies if she doesn't sell them.
