Based on true events.

The charming Walsh family moves to a new town from the other side of the country. Their youngest daughter Poppy easily makes... friends and becomes the most popular girl in class. But Poppy has a secret. Because of it, the whole family was bullied in their hometown, and they were forced to run away. Because of it, the Walshes pretend to be just ordinary in their new place, although that’s not the case. Because of it, Poppy befriends everyone, but keeps them at a distance.

Loneliness or popularity based on lies? Pretending to be someone you are not for the approval of others, or staying true to yourself, even if it's difficult? Poppy thinks she has a choice... until the town discovers her secret.
