Five‑year‑old twin girls Avery and Roxy sneak away from their mother Evelyn to track down their mysterious birth father Lucian, the powerful New York mafia don. Crawling out of city sewers, the clever pair break into his luxury hotel. Though malicious step‑relatives Grace and Serena repeatedly try to stop them by swapping DNA test samples and hiring impostor fake fathers, the multi‑talented little heroines use their hacker, investment and jewelry‑designer hidden identities to expose all conspiracies. Faced with kidnapping, assassination and gang power struggles, the brave twins assist Lucian in defeating hostile forces and internal traitors. Gradually the cold mafia boss transforms into a devoted “girl dad”. After clearing up the five‑year‑old misunderstanding between Lucian and Evelyn, the whole family defeats all villains. Finally Avery and Roxy are formally recognized as family heirs, and the four of them build a warm, complete family together.
