Crack trial lawyer Bennie Rosato is called to the local prison to consult with Alice Connolly, a woman accused of committing cold-blooded murder and who wants Bennie to represent her at the trial. Bennie has no intention of taking the case, until she comes face to face with Connolly: the incarcerated woman is a dead ringer for Bennie—and claims to be her long-lost twin sister. Disbelieving but somehow convinced, Bennie takes on the case against her better judgement, and starts sniffing out the corruption and dangerous cover-up that lies at its centre.
