Holly's twin sister Anne James lives in London with her mother Elizabeth James, who is a wedding dress designer. The sisters didn't know each other existed.

One summer vacation, Holly and Annie happened to attend the same summer camp. At first, they regarded each other as enemies, but they all shared some common characteristics: allergic to strawberries, good at playing cards, good at pranks, and fond of dipping biscuits in peanut butter. Once after they played a prank on each other, the counselor isolated them and let them live in the same dormitory. They soon discovered the secret of each other's lives. After that, they plan to exchange identities at the end of the summer camp and meet their parents they can't see.
