When Astrid (Danica Kurcic) receives a disturbing phone call on her radio program, she decides to return to her hometown to investigate the disappearance of her sister Ida (Karoline Hamm), which occurred 21 years ago, along with 17 other colleagues after an accident at the begin their graduate journey, in what constitutes a return to a traumatic past.
Equinox is a kind of languid fairy tale that crosses family drama, psychological thriller and elements of folk horror in a narrative that follows Astrid in her investigation of the present, her sister Ida in the weeks leading up to her trip and Astrid at that time ( Viola Martinsen), a 9-year-old girl who must face the trauma of her sister's disappearance.
This Danish series could have perfectly been developed into an hour and a half movie instead of a miniseries. I admit that I have problems with folk horror, which generally makes me laugh and I can hardly ever take it very seriously. Equinox does not display much information and only shows most of its relevant cards in its last sections, challenging the patience of the spectator determined to have the enigma revealed in several sections and culminating in a final that will divide waters.
Ida and her classmates are seen as half grown for high school students. Perhaps the most interesting characters are the haunting Lene, the sisters' mother, in charge of a remarkable Hanne Edelund and the girl Astrid with the odyssey of her visions and treatment of her.
It is striking the comparison with Dark, a series with which it has nothing to do, since the German is a sci-fi choral drama and not a fantasy and horror drama. Equinox can be related in its premise with the French series Les Revenants, although not in its development.
