The film stars Mark Rylance who leads an ensemble cast including Zoey Deutch, Johnny Flynn, Dylan O'Brien, Nikki Amuka-Bird, and Simon Russell Beale.

Rylance plays an English cutter who runs a tailor shop in Chicago, whose primary customers are a family of vicious gangsters.

In 1956 Chicago, Leonard Burling is an English cutter who runs a custom tailor shop in a neighborhood controlled by Irish Mob boss Roy Boyle.

Leonard is forced at gunpoint to treat Richie's wounds and hide a briefcase containing a copy of an FBI recording with detailed information on the crew's operations, which was provided by "The Outfit", a nationwide syndicate founded by Al Capone.

When Roy orders his men to torture her for information, Leonard distracts him by revealing the reason why he came to Chicago: his wife and daughter were killed in a fire at his former shop and home on Savile Row.

Leonard has been deceiving the Boyles by planting fake messages from The Outfit, and knew that Mable has allowed the FBI to place a bug in his store.
