Lady Eileen (Mia McKenna-Bruce) turns her grief into vengeance as she plunges hard to find the murderer of her love interest in the trailer for Netflix's Agatha Christie's Seven Dials. The trailer for the three-episode mini-series was unveiled on Tuesday.

The series is set in 1925 England. The plot revolves around a lavish party at a country house in which a prank contributes to a murder. Ultimately, it becomes the task of detective Lady Eileen “Bundle” Brent to solve the mystery.

The series also stars Martin Freeman and Helena Bonham Carter, who appear alongside McKenna-Bruce as Superintendent Battle and Lady Caterham, respectively. Corey Mylchreest also stars as the murder victim. The series is written by Chris Chibnall, best known as the showrunner of Doctor Who and the writer of Broadchurch, and directed by Chris Sweeney.

The series is described as an interpretation of Agatha Christie's eponymous novel. The story was earlier adapted into a television film, with Cheryl Campbell playing Brent. Suzanne Mackie is executive producing the series for Orchid Pictures, alongside Chibnall for Imaginary Friends, James Prichard for Agatha Christie Limited, Chris Sussman, and Andy Stebbing. On the other hand, Joanna Crow is producing it. The series will premiere on Netflix on January 15

This is the first major role in the career of McKenna-Bruce, who is known for playing Tara in the 2023 film How to Have Sex, which won the Un Certain Regard award at the Cannes Film Festival.
