Five-year-old Amaya disappears during a Christmas parade in Málaga and the case catches the attention of Miren, an intern at the local newspaper. When a little girl goes missing during a parade in Málaga, a young newspaper journalist becomes fiercely determined to help Amaya's parents find her.

In 2016, six years after Amaya vanished, a mysterious video reopens the case. In 2010, the police investigate a family friend with a suspicious past.

Diario Sur publishes the video of Amaya after Miren strikes a deal with Millán, leading to a flood of new tips and a potential suspect.

James Foster gives Miren disturbing information that opens up a new line of inquiry. In 2019, a second video appears, making Ana fear the worst.

The past nine years look very different from the perspective of Amaya's kidnappers. And as the search intensifies, they grow increasingly desperate.

Miren herself becomes a target of suspicion but refuses to give up on the search for Amaya, even when it takes her into serious danger.
