Still thinking about how Cuckoo (2024) ended? Here’s a full breakdown of the ending, key final moments, major twists, and the deeper meaning behind the film’s conclusion.
Gretchen’s journey in Cuckoo is deeply emotional, intertwined with themes of family, trauma, and acceptance. Throughout the film, she is haunted not only by supernatural entities but also by her feelings of abandonment and her desire for connection. The creature in the film, a humanoid monster resembling a bird-woman, represents a parasitic being that replicates the behavior of cuckoo birds—using shrill shrieks to disorient and trap her victims in a kind of time loop, then impregnating them with her offspring. This monstrous figure has lived in the forests surrounding the town for centuries, and the film reveals that her offspring are actually the children of humans, like Alma, Gretchen’s half-sister.
As the story unfolds, it becomes clear that Alma, the young girl Gretchen initially dismisses, is actually the product of her father Luis and the monster, making her a terrifying yet tragic link between humans and monsters. The resort owner, Konig, is deeply involved in experiments to preserve these creatures, hoping to understand and perhaps control their reproductive cycle. His experiments aim to find out if the monster can recognize her own offspring—her human daughter, Alma—and whether she would act or protect her.
In the climax, Gretchen’s emotional growth leads her to see Alma not just as a monster, but as her sister—an individual who, despite her supernatural origins, is capable of genuine feelings. When Henry and Konig threaten to kill Alma to further their selfish aims—Konig for his experiments and Henry out of fear—the girl’s true nature emerges. Alma uses her powers, including her shrill shriek, to escape and ultimately help Gretchen and herself flee from danger. Gretchen’s decision to save Alma signifies her acceptance of family and love beyond societal labels, recognizing that the true monster lies in the cruelty and indifference of the men who seek to exploit these beings and destroy their genuine emotions.
The ending hints at the ongoing danger, as Alma’s ears twitch, suggesting that she is still a monster beneath her human-like exterior. Yet Gretchen’s act of compassion embodies a rejection of fear and prejudice, emphasizing that empathy and understanding can challenge even the most terrifying monsters. The film concludes on a note of cautious hope—while the threat is not fully eradicated, Gretchen’s choice to embrace her sister’s humanity and her own emotional vulnerability offers a powerful message about kinship, acceptance, and the complexity of what it really means to be human.
