Lucy, a highly‑skilled girl trained by a hermit master, is sent to New York to track down her five long‑lost elder brothers. The five brothers hold top‑tier positions respectively: a Wall‑Street tycoon, a superstar football player, a Hollywood movie star, a MIT quantum genius and a powerful political figure. Arriving in the bustling city with only an old canvas bag, Lucy visits them one by one. She hacks financial systems, solves sports injuries, composes brilliant piano music, fixes quantum‑lab failures and uncovers political conspiracies. Though repeatedly framed by the scheming Vivian, she wins her brothers’ recognition. Finally, the five powerful brothers all dote on their unexpected little sister.
