The four women embark on a series of successful bank robberies, due to Frankie's inside knowledge of bank protocol with money and security. An investigation by LAPD Detective Strode ensues. Strode suspects that Cleo (because of her prior convictions), Frankie (because of her inadvertent connection to the earlier robbery and subsequent firing) and Stony (because of her brother's death) are involved. But his superior refuses to allow him to bring them in for questioning because he doesn't feel the evidence is sufficient. Concerned with the safety of their money, the four women stash the money in an air vent at one of their work sites.
