Hacker queen Scarlett vanished five years ago to escape enemy Black Mamba, secretly giving birth to three genius triplets. When a hack on Li Group blows her cover, she sneaks in as a bumbling assistant to lay low—and discovers CEO Li Tingshen has a severe touch allergy, yet she is the only exception. Her three kids run remote backup: eldest hacks the DNA test, middle fakes photos of her "boyfriend," youngest fires pepper spray from a drone. Team "Troll Dad" activates. Li Tingshen pieces together her identity and, to save her and the children, prepares to surrender his billion‑dollar empire. The family of five takes down the villain together. The triplets put their "intern dad" through hilarious trials; he finally passes, earns his title. A grand wedding, all threats gone—happily ever after.
