Recently paroled master thief Daisy "Jett" Kowalski looks to go straight to provide normal lives for her young daughter Alice and her best friend Maria. Instead, she's enlisted by former employer/part-time paramour Charlie Baudelaire to steal a ring from an Eastern European overlord named Miljan Bestic, living in Cuba. Jett won't agree to the job without her former partner Quinn, a safecracker who's still serving three years in the slammer, so Baudelaire engineers an escape involving the kidnapping of a prison warden's wife. After running into Jack Dillon, an undercover cop with a vested interest in Baudelaire and his loose-cannon son Junior, Jett travels to Cuba with Quinn, where the pair embarks on a dangerous cat-and-mouse game with Bestic.

Shaken from her job in Cuba, Jett is approached by a Bestic subordinate, Evans, about masterminding a heist at the site of a high-stakes poker game. A skeptical Jett agrees, and is forced to work with a pickup gang of thieves, including a man named Blair who once tried to kill her. Meanwhile, Charles Junior continues to make enemies in high places, as a turf war between Baudelaire and cartel kingpin Jacinto Salas escalates. Accompanying Maria on a hospital visit, Jett recalls their introduction seven years earlier, when both were coping with very different travails.

Jett looks back at the in-prison altercation that forged an out-of-prison bond with a former junkie hooker named Phoenix. Searching for intel on Junior's connections, Dillon and Josie put the sting on his underling, Bobby. Baudelaire's rival, Jacinto Salas, gets an unsettling warning while visiting his ailing mother at the hospital. Hoping to uncover details on the relationship between Junior and Bestic, Jett pays a visit to an imprisoned former mentor, crime boss Carlyle. A suspicious Evans orders Jett to track down Blair – or face the consequences.

As she tracks down Frank Sweeney, a gangster known for using a nail gun on his enemies, Jett recalls the job when the two met – before Jett went to jail and Sweeney was paralyzed for life. Meanwhile, an intruder wrecks Baudelaire's 19th-hole lunch; Jett gets information from a double-crossed Blair; Phoenix is rewarded for babysitting Alice; and Evans delivers a message to Junior.

Fearful of Tucker, Rosalie decides to take matters into her own hands, forcing a vigilant Bennie to intervene. After a visit with Baudelaire, Jett is briefed by Evans on a new job, even as her two bosses' paths seem to collide. Jett remembers back six years earlier, when she enlisted Maria to execute a unique in-prison heist. Josie risks blowing her cover after running into Bobby and Junior outside a church. A debt paid, Phoenix auditions for a new job, Bennie cleans up a mess. Evans briefs Jett on a new job for Bestic.

Reconnecting with McKay, a fellow con she met on a diamond heist with Quinn, Jett orchestrates the heist of a vintage Mercedes from a tony lakeside estate. The plan goes smoothly enough – until a pair of interlopers crash the party. Meanwhile, Josie tries to break things off with Dillon, but ends up being sucked into a dangerous game with Junior and his henchmen, Taggart and Hopper.

Bennie finds himself keeping close company with an unhinged Rosalie. Dillon gets bad news from Carter, and sets his sights on exacting revenge. Jett is forced to overcome a major detour before reuniting with McKay and completing her latest job for Evans. Charlie grows increasingly suspicious after a heist goes awry.

Jett finds herself in dire straits when Dillon, hell-bent on revenge, descends on Charlie’s house to confront an out-of-control Junior, who has come to his father for help. Phoenix deals with her brother Neal’s threats head-on. Later, Jett remembers her last heist with Quinn and a crucial tête-à-tête with Dillon, before hearing Bestic’s final demand.

Before a fateful meeting with Bestic, Jett sets in motion a plan to be free of him for good. When the two come face-to-face, Bestic reveals the origins of his feud with Charlie. As the situation becomes increasingly perilous, Jett realizes she’s in danger of losing the very thing she holds most dear.
