On the day of the wedding of a medical student with a wealthy plastic surgeon, the families of the young couple realize that the only thing they have in common are secrets and lies. The secrets of both sides will be revealed during the wedding ceremony.
Already on opposite sides of Michael Hewes's custody suit against his mother, Patty Hewes (Glenn Close) and Ellen Parsons (Rose Byrne) prepare to face off in court after a cyber-hacker's revelations about insider trading expose damaging personal information that push an informant over the edge.
Three years have passed since Patty and Ellen last worked together. Ellen reconnects with her high school friend, Chris Sanchez, who has recently returned from a stint at High Star, a private contractor in the Middle East. Unable to get assistance from the corporation or the government, Ellen decides to look into his case. Both her new boss and Patty warn Ellen about building a case against High Star Security Corp.
Almost a year has passed since Ellen Parsons left Hewes and Associates. She is now working in the District Attorney's office and is dealing with a fairly important drug case, trying to get a dealer to reveal the identity of his supplier. Patty Hewes is now acting on behalf of a group of investors trying to recover money they had entrusted to Louis Tobin and who, it turns out, was running a Ponzi scheme. With billions of dollars unaccounted for, Patty is trying to find any funds that may have been hidden by the Tobin family. Patty and Ellen have had no contact since her departure but Patty has been reluctant to re-assign her office, convinced that Ellen will return. She even sends her an expensive handbag. Ellen wants nothing to do with her however and when she thinks Patty may be interfering with her drug case, tells her she doesn't need any help. She also tells her that any secrets she may have are perfectly safe. In a flash-forward 6 months into the future, Patty Hewes is in a serious accident when another car broadsides her vehicle in an intersection. The occupant of the other vehicle has fled but it is registered to someone she knows.
Three months after the Frobisher settlement, Patty is concentrating on establishing a charitable foundation when an old boyfriend, named Daniel Purcell, contacts her and entangles her in a new case involving corporate fraud and greed. Meanwhile, Ellen continues working with the FBI to destroy Patty, but she becomes more rash and impatient as she continues to set up her appearances to hide her rage behind fabricated grief in the wake of David's murder. Elsewhere, Arthur Frobisher is revealed to have survived the assassination attempt and is recovering in seclusion as he plots his next move against all the people whom he felt wronged him.
