Best friends Nancy, Bess and George want to raise money to buy tickets to their favourite singer's concert. To do this, they start selling lemonade according to the recipe of Anna, the housekeeper in Nancy's family. The recipe for pink strawberry lemonade has always been kept secret in Anna's family. But a piece of paper with the recipe mysteriously disappears from under the girls' noses. Has someone stolen it? There are many takers: Lily, who has also set up a lemonade stand in her yard, and the girls' classmates, who want to win a cooking show on television. It's time for the Detective Team to get down to business!
