The addictive new thriller series from Atomic Monster, also starring Karla Souza and Dorian Missick, will premiere Wednesday, February 18, 2026, exclusively on Prime Video
Today, Prime Video released first-look images and announced the premiere date for the highly anticipated new thriller series, 56 Days, adapted from Catherine Ryan Howard’s best-selling novel. All eight episodes will be released on Wednesday, February 18, 2026, exclusively on Prime Video in more than 240 countries and territories worldwide.
56 Days follows Oliver and Ciara, who, after meeting randomly in a supermarket, fall for each other fast, and dangerously hard. Fifty-six days later, homicide investigators arrive at Oliver’s apartment to find an unidentified body – brutally murdered and intentionally decomposed. Did he kill her? Did she kill him? Intercutting between an intense single day in the present investigation, and the twisted trajectory of the young lovers’ affair in the past, the series is both a unique crime story and a riveting, sexy, psychological thriller.
The star-studded cast features Dove Cameron as Ciara Wyse, Avan Jogia as Oliver Kennedy, Karla Souza as Lee Reardon, and Dorian Missick as Karl Connolly.
56 Days is written and executive-produced by Lisa Zwerling and Karyn Usher. Also executive producing are James Wan, Michael Clear, and Rob Hackett via Atomic Monster, with Danielle Bozzone overseeing the series on behalf of the company. Catherine Ryan Howard will serve as co-executive producer. The series is produced by Amazon MGM Studios and Atomic Monster.
