Plot Synopsis

Sara, a female photographer, begins a torrid affair with Jack, a lawyer for a powerful family, and the new lovers learn that they're on opposite sides of the murder trial of the century, resulting in a series of betrayals with cataclysmic results. Sara has been unhappily married to Drew, a successful lawyer with political aspirations, who takes this case because a victory can elevate his career. Jack is married to Elaine, the daughter of Thatcher Karsten, the patriarch of a powerful Chicago family. When Thatcher's brother-in-law Lou is found murdered, the evidence points to his mentally challenged son, TJ, and Jack defends his own brother-in-law, while protecting the Karsten family name. Despite these events, Sara and Jack both realize something is missing in their marriages, fight against the realization that they've met their soul mates in one another, and try to resist the powerful pull of their affair.
