Sophia and her friends are having a great time at the coding class. They learn a lot about programming, but they also have time to help out at soccer matches, act and talk about boys... They enter a coding marathon where they have to build a robot, while they also get to know students from other schools. It's time to take joint work seriously!
They are well into their preparations for the marathon when one of their team members faces an unexpected difficulty. Will the girls succeed or fail? They've already learned that programming is about solving problems and teamwork - but maybe the same is true for friendship!
