Six‑year‑old Mia is born with superhuman strength and lives only with her mother Chloe. Suffering from heart failure, Chloe urgently needs a million‑dollar heart transplant. Mia joins an extreme street challenge, lifts a two‑ton off‑road vehicle with one hand and wins the prize money — yet it is still not enough to save her mother’s life.Learning that the Sterling family is offering a million‑dollar reward to hire a top‑tier caretaker for their heir Arthur, she marches straight into their manor. The elderly couple are won over by her liveliness and stubbornness, and lead her to Arthur’s room. Just as Mia is about to show off her caregiving skills, she realises the cold‑hearted employer in the wheelchair is none other than the father who made her mother shed tears.
