In Lemonade Mouth, the five students first meet during detention.
The 2011 Disney Channel musical follows Olivia White, Mo Banjaree, Charlie Delgado, Stella Yamada, and Wen Gifford. They are brought together in after-school detention for separate reasons, placing five otherwise different students in the same room. While the supervising music teacher briefly leaves, they begin making music together and discover a shared creative spark.
That punishment becomes the story’s turning point. The students eventually form a band and enter school performances, using music to challenge school policies and deal with personal problems. The film was directed by Patricia Riggen and adapted from Mark Peter Hughes’s 2007 young-adult novel.
The answer is sometimes confused with the later police detention in the plot. The group does get detained after protesting the removal of the school’s lemonade machine, but that occurs after they have already met and formed their musical bond. Probation, expulsion, and suspension are not the punishment that introduces the five central characters.
