56 Days, a gripping psychological thriller now streaming on Prime Video

56 Days, a gripping thriller adapted from Catherine Ryan Howard's novel, starring Dove Cameron and Avan Jogia, will be available on Prime Video starting February 18, 2026.

56 Days is a thriller series based on the novel by Catherine Ryan Howard, set to premiere on February 18, 2026 on Prime Video. Produced by Amazon MGM Studios and Atomic Monster, the show is developed by Karyn Usher and Lisa Zwerling, who also serve as executive producers alongside James Wan, Michael Clear, Rob Hackett, Danielle Bozzone, and Sandrine Gros d’Aillon. The cast features Dove Cameron, Avan Jogia, Karla Souza, and Dorian Missick.

The story follows Oliver and Ciara, who cross paths unexpectedly in a supermarket and quickly plunge into a relationship marked by intensity. Their instant chemistry leads them to retreat from the outside world, cultivating a passionate, exclusive bond. Six weeks later, criminal investigators uncover an unidentified, brutally murdered body in Oliver’s apartment, deliberately left to decay.

The narrative switches between a pivotal day in the investigation, set in the present, and the timeline of the couple’s past relationship. This back-and-forth structure gradually uncovers hidden motives, manipulations, and lies. The viewer is faced with a central question: who killed whom? By relocating the story to Boston instead of Dublin, as in the original novel, the adaptation shifts away from the pandemic setting to offer a contemporary backdrop detached from the health crisis.

The series is crafted as a standalone crime drama, deliberately set apart from any Covid-19 or quarantine-related plotlines, despite its literary roots.
