A last chance met at the edge of a cliff, a new beginning, not an end. In the K-POP market where the average debut age is getting lower, youth who haven't given up on their dream of being idols in their late twenties. Not a survival audition where they fight and compete, but a humanistic growth project where one can only win the crown by winning the battle against oneself! Through the reality growth project <Fly, Chick!>, the 9 trainees who have once again earned the chance to debut, their record of blood and sweat poured out to prove themselves, trainees who haven't even gotten a name yet. A reality program that captures their sincere growth from 0% to 100%. The last chance given to the twenty-somethings who want to stand on stage once again, breaking the world's prejudice that it's too late! The fierce challenge of the chicks, who will spread their wings powerfully towards their dreams, begins.
