A seven‑year‑old girl with extraordinary mechanical talent grows up as a laborer in a repair shop, dreaming of becoming a professional racer. Reunited with her wealthy birth family, she is harshly dismissed by her status‑obsessed father, who reserves all racing resources for her favored younger brother. After accidentally crashing into a mafia‑run site one night, she gains five powerful guardians who supply her with cars, coaching and protection. Facing unfair disqualification, sabotaged race cars and dirty tricks from her own family, she never relies on her backers to win. Relying on her gift for machinery, sharp track judgment and indomitable will, she fights through fierce youth‑level tournaments and finally snatches the championship by a tiny margin in a brutal rain‑soaked final.
