The BBC America series premieres this April

“I know you are an extraordinary person,” Sandra Oh’s Eve says to begin the first trailer for Killing Eve. “I know something happened to you. I know you’re a psychopath.”

It’s an appropriately hair-raising introduction to the upcoming BBC America thriller, which is due to premiere this April. Killing Eve explores the relationship between Eve — a bored, whip-smart, pay-grade MI5 security officer whose desk-bound job doesn’t fulfill her fantasies of being a spy — and Villanelle (Jodie Comer), a mercurial, talented killer who clings to the luxuries her violent job affords her.

The show was developed by Phoebe Waller-Bridge, marking her anticipated follow-up to Fleabag, the Amazon dark comedy which drew raves. She also previously created the British series Crashing.

Fiona Shaw (Harry Potter, True Blood), David Haig (Four Weddings and a Funeral, Penny Dreadful), and Kim Bodnia (The Bridge) co-star in the drama. Watch the unnerving teaser above, and look out for the show’s BBC America premiere on April 8 at 8 p.m. ET.
