A street girl who mistakenly wore the jersey of a wealthy club exploded the professional arena with her wild playing style, tearing apart the hypocritical mask of sports capital. She is not a genius, but she knows football better than anyone else; he is not a traitor, but he is willing to betray his bloodline for her. The coach secretly recorded her tactics, the point guard covered her loopholes, and the old scout hid evidence that was buried twenty years ago. When the league's top brass launches the 'Purge Plan', this accident of wearing the wrong jersey is evolving into a war to rewrite the rules.
