The Understudy

They tried to protect their children—and to do so, handed their freedom over to an algorithm.

2027. A new product hits the market: “Doubler,” an advanced parental-control app. It listens to everything happening near the child, tracks their messages, predicts threats in advance, and instantly blocks dangerous scenarios. Almost flawless digital protection.

But when seventeen-year-old Renata disappears right after going to the movies, “Doubler” for the first time gives no answers at all. No leads, no traces—only a turned-off phone and a strange system glitch. While the police are stuck in place, volunteers join the search, including students. And the further they go, the more obvious it becomes: the disappearance is linked not only to Renata, but also to the very idea of total control—and probably to those behind the app’s creation.

A dynamic psychological thriller about the limits of trust, the dark side of technology, and the price of security. For fans of “Black Mirror,” “Gone,” and “Mr. Robot.”
