A whirlwind romance, a decomposing body, and two detectives racing to figure out who’s the killer and who’s the victim before the truth catches up.
56 Days is a Prime Video psychological thriller that combines a fast-moving romance with a murder investigation told across two timelines.
This blog covers the cast of 56 Days, the characters they play, the recurring actors, and the main writers, directors, producers, and crew members behind the series.
What is 56 Days About?
56 Days is an eight-episode psychological thriller and murder mystery released on Prime Video in 2026. The series is based on Catherine Ryan Howard’s bestselling novel of the same name.
Oliver Kennedy and Ciara Wyse meet by chance at a supermarket, and their relationship quickly becomes serious.
Their romance feels exciting at first, but it’s not simple. Fifty-six days later, police find a body in Oliver’s apartment.
Detectives Lee Reardon and Karl Connolly examine the couple’s past to determine who died, who may be responsible, and what happened during the previous 56 days.
The show jumps between their love story and the murder case, so you’re always piecing things together.
The shifting timeline keeps important details hidden until later episodes, making the series suited to viewers who enjoy slow-burn mysteries.
