Heathers meets The Stepford Wives in this creepy and frighteningly funny dark thriller about a woman who will do anything to find her missing sister. Even pretend to be one of them.

After her twin sister, Chiara, goes missing at a mom-fluencer weekend, Adrienne Shaw will find her no matter what it takes. They may have been on the outs, but no one comes for her sister and gets away with it.

It’s been a year, the authorities have no answers, and her brother-in-law is useless in the matter. It’s time for Adrienne to take the case into her own hands. Following in Chiara’s last footsteps, Adrienne goes undercover, infiltrating the same influencer retreat as the last thing she wants to be: an Instamommy.

The remote ranch in Northern California is certainly welcoming—in a cult-adjacent kind of way. A charismatic leader, communal crafts, fixed smiles—and a lot of dead eyes.

Going on gut instinct and chasing a wild theory—that Chiara came here and never left—Adrienne is determined to uncover the truth before the too-perfect-to-believe women figure out who Adrienne really is: a threat to be eliminated.
