In the cushy cul-de-sacs of Ashton Pines, Tanner Whitmore is every parent’s nightmare: a fully grown, unemployed 18-year-old baby-man living off energy drinks, mom's credit card, and TikToks about lizard people. When his exasperated parents hire a rogue “nanny” off a sketchy parenting site, they get more than they bargained for — Gunnar Steele (Dwayne Johnson), an ex-Navy SEAL with a buzzcut, no chill, and a laminated life plan titled "Operation: Grow the Hell Up."
As Tanner struggles to survive 5AM obstacle courses and simulated job interviews, and Gunnar fends off nosy neighbors, suspicious mayors, and viral fame, both man-child and man-mountain begin to change — for the better. But when a nanny ban threatens to tear them apart, it’s up to Tanner to prove he’s finally grown... just enough.
