When the fictional adventures of larger-than-life secret agent Argylle attract the attention of an actual spy syndicate, reclusive author Elly Conway becomes unwittingly embroiled in international intrigue where her imaginary creations cross the line with reality. Saving Elly's life requires a daring race against the clock while unlocking the incredible mystery in her mind. The romantic action-comedy thrill ride from the twisted mind of director Matthew Vaughn (the Kingsman films) takes more than a few truly novel turns with a top-flight cast that includes Bryce Dallas Howard, Sam Rockwell, Henry Cavill, John Cena, Ariana DeBose, Dua Lipa, Bryan Cranston, Catherine O'Hara, Sofia Boutella, and Samuel L. Jackson.
