Do Not Babysit These Kids. You've Been Warned

A babysitter named Sienna takes a job watching three five-year-olds for $350 per child per night, only to discover that the children are actually adults in their twenties who have been physically regressed by their mother. The story follows Sienna as she pieces together the horrifying truth: Mrs. Hawthorne, a controlling perfectionist, turned her adult children back into toddlers because they failed to meet her expectations, and Sienna herself is about to become the next victim.

The episode opens with Sienna living at home after a breakup, trapped between her mother's relentless pressure to have children and her own complicated feelings about family. When her mom shows her a Facebook babysitting post offering $350 per child for three five-year-olds, Sienna reluctantly agrees, partly to escape her mother's nagging and partly because the money is too good to ignore. The post's author, Sunny Hawthorne, describes her children as "three well-behaved five-year-old darlings who you will immediately fall in love with," but Sienna's instincts warn her that something is off.
