Harry Rawlings, a renowned thief, is killed alongside his partners Carlos, Florek, and Jimmy during a botched robbery. His widow, Veronica, is threatened by crime boss Jamal Manning, from whom Harry and his partners robbed $2 million. Jamal needs the money to finance his electoral campaign for alderman of a South Side precinct, where he is running against Jack Mulligan, the next-in-line of the Mulligan political family who have historically dominated the alderman position. Veronica discovers Harry's notebook, which contains a detailed plan for a heist worth $5 million. She decides to carry out the plan to repay her debt to Jamal, and recruits two of the other widows, Alice and Linda, to assist her. The fourth widow, Amanda, does not show at their initial meeting; when Veronica visits Amanda and learns she has a newborn child, she opts not to mention the heist plan to her. Alice buys the getaway car and guns, while Linda is tasked with deciphering a blueprint in Harry's plan. Alice uses David, a real estate executive with whom she is in a transactional relationship, to identify the blueprint as a safe in Jack Mulligan's home.
