AceShowbiz - Neon has unveiled a chilling trailer for their upcoming thriller "Cuckoo", starring "Euphoria" actress Hunter Schafer. The 25-year-old transgender actress, who recently sparked headlines for her comments on avoiding transgender roles, plays Gretchen in the enigmatic film.

"Cuckoo" follows Gretchen and her parents (Jessica Henwick and Marton Csokas) as they move into a seemingly idyllic resort in the German Alps. However, Gretchen soon discovers that this bizarre place holds sinister secrets. As she is plagued by strange noises and bloody visions, Gretchen uncovers a shocking truth that implicates her own family.

The trailer opens with Gretchen confessing her desire to return home due to the disturbing nature of the resort. The family's journey to the resort is filled with eerie moments, including a strange encounter with Mr. Koning (Dan Stevens), her father's boss. Koning displays an inexplicable interest in Gretchen's mute half-sister, Alma (Mila Lieu).

Gretchen's suspicions grow when she witnesses a disturbing incident at the resort's reception area. She is forced to lock the doors and wait for Koning's arrival, after which she witnesses a young girl's shadow lurking behind her.

The trailer also features scenes of Gretchen in a hospital with a head bandage and a brace on her arm, suggesting the horrors she experiences at the resort. Koning warns her that she could face further harm if she does not comply with their preservationist agenda.

"Cuckoo" marks Schafer's first horror film and her third major acting role. The trailer showcases her intense performance as the hunted protagonist, evoking comparisons to "The Shining." The film also stars Stevens as the enigmatic villain and Henwick as Gretchen's stepmother.

Directed by Tilman Singer, "Cuckoo" premiered at the Berlin International Film Festival and South by Southwest, receiving positive reviews. It is set to hit theaters on August 9, promising a thrilling and unsettling cinematic experience.
