Why I’ll be tuning in

This twisty psychological thriller promises a murder mystery with a compelling narrative structure, with the present day investigation intercut with a past romance that rapidly escalates over 56 days. While the two leading stars are certainly a draw for viewers, the show’s strength perhaps lies in its source material, Catherine Ryan Howard’s bestselling novel, which is already hugely popular.

Plus, viewers can expect high production quality, with James Wan’s Atomic Monster (I Know What You Did Last Summer) producing alongside Amazon MGM Studios.

What is 56 Days about?

The story centres around Oliver and Ciara, who, after meeting randomly in a supermarket, fall for each other fast, and dangerously hard. Fifty-six days later, homicide investigators find an unidentified and brutally murdered body, which is intentionally decomposed, at Oliver’s apartment. Did he kill her? Did she kill him?

The synopsis continues: “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.”

Who stars in the series?

Dove Cameron, known for her roles in the Disney children’s show Liv and Maddie, Dumplin’ and Agents of S.H.I.E.L.D., stars as Ciara Wyse. She’s joined by co-star Avan Jogia, who also rose to fame as a child star on shows like Victorious and the TV film A Girl Like Me: The Gwen Araujo Story, before later starring in series including Twisted and Now Apocalypse.
