Elly Conway (Bryce Dallas Howard) is the reclusive author of a series of best-selling espionage novels centred on a secret agent named Argylle (Henry Cavill) and his ongoing mission to unravel a global spy syndicate. But none of it is real… or is it? When her supposedly made-up plots begin to mirror the covert actions of a real-life spy syndicate, Elly and her beloved pet cat find themselves on the run and in genuine danger as her fictional world and the real one begin to blur.

With an all-star cast including Sam Rockwell, Bryan Cranston, John Cena, Ariana DeBose, Dua Lipa and Samuel L. Jackson, this reality-bending spy thriller is the latest film from director Matthew Vaughn (Kingsman, Kick-Ass). Needless to say, it’s best seen without the cat having been let out of the bag.
