Four-year-old genius hacker Mia disguises herself as a mentally disabled orphan and breaks into the mansion of her biological father, Richard, a billionaire. Three years ago, Richard personally unplugged his critically ill ex-wife’s ventilator to raise startup capital. Clutching the IOU for 3.57 yuan for milk that her mother slipped to her on her deathbed, and accompanied by a chubby orange cat with a missing ear, Mia sets a series of traps throughout the estate. She exploited surveillance blind spots to steal crucial evidence, used the cat’s claws and traps to take down the hitman hired by her stepmother, and ignited a family feud with a simple sketch. Finally, at the Nasdaq bell-ringing ceremony, she projected irrefutable evidence of her biological father’s murder onto the big screen in front of the global media, causing his 10-billion-yuan empire to collapse instantly, and then personally threw the 3.57 coins in his face.
