The supernatural thriller is directed by Søren Balle (Sunfish, The Rain) for Piv Bernth’s Apple Tree Productions.

Filming of the six-part series just started in Denmark.

The latest Netflix Danish original is based on the acclaimed podcast Equinox 1985, adapted for the screen by Tea Lindeburg. Danica Curcic (The Bridge, Warrior) plays Astrid, who is affected by the unexplainable disappearance of her sister and her school class in 1999.

When the one survivor from 1999 mysteriously dies, Astrid is determined to find out what happened to her sister and the class.
