The girl Christine (Saoirse Ronan) followed her family to a church school in California to start her high school career. Although she was unwilling in her heart, Christine still did not have enough strength to resist the arrangements of her family and life. In school, Christine's best friend is Julie (Beanie Feldstein), and the two people with similar values can talk about everything. Christine participated in a stage play competition and met a boy named Danny (Lucas Hedges), and the two people who were attracted to each other soon came together. However, this relationship ended in a breakup. In order to get close to Jenna (Odeya Rush), a campus socialite, Christine lied, but unfortunately, lies could not be exchanged for true friendship. When Christine was caught in an emotional entanglement with Kyle (Timothée Chalamet), her family was also going through a difficult time.
