體重超標的Terri穿睡衣上學，種種心不在焉的行為經常受到同學無情的嘲笑，本想默默承受，沒想到卻引起副校長Fitzgerald的注意。他使出各種方法來幫助Terri，偶爾弄巧成拙，但也促成Terri交了兩個朋友：用叛逆行為來掩飾沒安全感的 Chad，以及過於早熟的辣妹Heather。三個外表完全不同但同樣被排擠的局外人變成好友，一同經歷青春期的酸甜苦辣。
Terri is an often bullied, overweight teen. When he decides to stop trying in school, the garrulous principal, Fitzgerald, becomes concerned. However, what was meant to be a counselling course for Terri becomes a journey of healing for both protagonists.
