Sunshine has been fighting on the side of justice since she was little. Cherry is a mute girl who eschews spoken words for messages scribbled on paper planes to communicate her thoughts. A war has been declared on an odiously fawning principal, an overbearing PTA chairman (and overprotective father of Cherry), a team of opportunistic teachers and a class of students innocent no more! Teaming up with a tech-savvy mentor (the school janitor), a range of DIY gadgets and the occasional indulgence of mischievous acts, Cherry conducts a series of covert operations and comes to Cherry’s rescue at a choral speaking competition.
