Prime Video has dropped the official trailer and key art for its upcoming erotic psychological thriller 56 Days, instantly sparking excitement among fans of dark romance and crime dramas. Adapted from Catherine Ryan Howard’s best-selling novel, the eight-episode series is set to premiere exclusively on Prime Video on February 18, 2026, streaming in over 240 countries and territories worldwide. With its sultry atmosphere, fractured storytelling, and shocking twists, 56 Days promises a gripping tale where love and danger collide.
The newly released trailer paints a haunting picture of intimacy turning sinister. What begins as irresistible attraction soon morphs into secrecy, obsession, and violence. Positioned as a high-stakes psychological thriller, the series explores how passion can blur moral boundaries and how quickly trust can become fatal. Creators and executive producers Lisa Zwerling and Karyn Usher, who adapted the novel for screen, shared that the story delivers “a sexy, emotional thrill ride where everything pays off in the end,” crediting author Catherine Ryan Howard’s gripping source material.
At the center of the story are Oliver and Ciara, two strangers whose lives change after a chance encounter in a supermarket. Their connection is instant and consuming, pulling them into a whirlwind romance that grows deeper and more intense with each passing day. However, exactly 56 days later, the story takes a terrifying turn. Police arrive at Oliver’s apartment to find an unidentified body brutally murdered and left to decompose, setting off a chilling homicide investigation.
The narrative unfolds across dual timelines, alternating between the present-day police inquiry and the past that traces the evolution of Oliver and Ciara’s relationship. As clues emerge, suspicion falls on both lovers. Did Oliver kill Ciara? Did Ciara kill Oliver? Or is the truth far more twisted than anyone expects? The structure keeps viewers questioning every moment and every motive.
Dove Cameron takes on the role of Ciara Wyse, while Avan Jogia stars as Oliver Kennedy. They are joined by Karla Souza as Detective Lee Reardon and Dorian Missick as Detective Karl Connolly, forming a cast that balances emotional vulnerability with investigative intensity.
Behind the scenes, 56 Days boasts powerhouse talent. Lisa Zwerling and Karyn Usher serve as writers and executive producers. Horror maestro James Wan, along with Michael Clear and Rob Hackett, produces under the Atomic Monster banner. Catherine Ryan Howard also joins as co-executive producer, alongside Sandrine Gros d’Aillon. The series is produced by Amazon MGM Studios in collaboration with Atomic Monster.
With erotic tension, psychological depth, and a murder mystery at its core, 56 Days is shaping up to be one of Prime Video’s most daring and talked-about thrillers of 2026.
