Seven‑year‑old genius girl Daisy was raised in seclusion deep in the mountains by her master. She is proficient in hacking, machinery, physics and chemistry, though she has a knack for causing explosions. Her master sends her to New York to track down her four long‑lost biological brothers from the powerful Sterling family.
Daisy seeks out each of her high‑status brothers one by one. Along the way, she fends off financial hacker attacks, basketball‑court schemes, and a lab reactor meltdown. She also falls victim to schemes plotted by the villain Celeste. Initially refusing to acknowledge her, the brothers gradually witness her extraordinary talents, accept her wholeheartedly, and fiercely protect her. Together they unmask the mole‑like villain, reunite at the family manor, and embark on a heart‑warming, hilarious life filled with doting sibling affection.
