Penny doesn't stand out and she likes it that way, but when she has a panic attack in English class, suddenly, she's very much in the eye of her classmates. To make matters worse, a classmate recorded it on Snapchat, which went viral around the school with "#PennyPanic." As the nickname is chanted at her in the halls, she clings to her friends but they all have their own struggles too. She feels alone and fears no one will understand her pain. She has Ms. Peese, a school counselor and a hippie Grandma, Betty, who guides her along the way to help normalize her anxieties. Penny begins to learn anxiety shows up differently for everyone; sometimes it's obvious and other times it's not. When the worst thing imaginable happens to one of her friends, will she be able to rise above it and reclaim her confidence or will the anxiety win?
