When math genius Emma and her coding club co-president, George, are tasked with brainstorming a new project, The Code for Love is born.

George disapproves of Emma's idea of creating a matchmaking app, accusing her of meddling in people's lives. But all the happy new couples at school are proof that the app works. At least at first.

Emma's code is flawless. So why is it that perfectly matched couples start breaking up, the wrong people keep falling for each other, and Emma's own feelings defy any algorithm?
