What Happens at Night is a chilling horror-mystery that masterfully blends psychological tension with atmospheric dread. The film follows an American couple whose journey to adopt a child in a remote, snowbound European town becomes a surreal nightmare. Director Peter Sobczynski creates an unsettling ambiance from the opening scenes, using the isolating white landscape and the claustrophobic, ornate hotel as characters in themselves.

The couple's performances are raw and compelling, portraying a marriage strained by hope and desperation. Their encounters with the hotel's bizarre residents—a haunting chanteuse, an enigmatic businessman, and a mysterious faith healer—are where the film truly excels. Each interaction peels back layers of the couple's psyche and the town's hidden truths, blurring the line between reality and hallucination in a way that recalls classic psychological thrillers.

Viewers should watch What Happens at Night for its meticulous pacing, haunting score, and thought-provoking exploration of parenthood and identity. It's a film that lingers, asking questions about what we pursue and what we become in the process. The final act delivers a payoff that is both ambiguous and deeply satisfying, making this a must-watch for fans of atmospheric horror and intelligent storytelling.
