Full Summary

Jane Smith, a tough-as-nails criminal defense attorney working in the Hamptons, has just landed the biggest case of her career: defending Rob Jacobson, heir to a publishing and real-estate fortune, accused of executing the Gates family in their rental home. As the trial is about to begin, Jane visits her lifelong friend Dr. Samantha Wylie for a routine follow-up. The news is devastating: advanced brain and neck cancer that has spread into her lymph nodes. Sam gives her a worst-case prognosis of one year, but Jane plea-bargains for fourteen months, delaying treatment to finish the trial.

In the courtroom, prosecutor Kevin Ahearn presents DNA and fingerprint evidence placing Jacobson at the scene, but Jane argues there is no motive. The trial swiftly becomes a battle of performance and deception. Surprise witnesses emerge: Nick Morelli, a fishing guide who saw Jacobson with the teenage victim Laurel Gates; Gus Hennessy, a real-estate mogul who claims he overheard Jacobson threatening the father; and Otis Miller, a decorated veteran who identifies Jacobson as the man speeding away from the crime scene. Jane attacks each one, exposing Hennessy’s hidden affair with Jacobson’s wife, Claire, and suggesting Miller may have had his own motive.

Outside the courtroom, Jane’s investigator and close friend Jimmy Cunniff takes on a cold case assigned off the books by District Attorney Gregg McCall: the Carson family murders. The investigation soon points to a loan shark, Bobby Salvatore, and a corrupt ex‑NYPD fixer named Joe Champi. Jimmy discovers that Champi, long rumored dead, is connected to both the Carson killings and the disappearance of McCall. A campaign of intimidation begins—shots fired at Jane, her dog Rip muzzled, Jimmy’s bar burned, and Jimmy himself ambushed and shot. Champi’s reach seems unlimited.

Jane’s personal life splinters as well. She adopts a stray black Lab she names Rip (short for “rest in peace”) and begins a relationship with veterinarian Dr. Ben Kalinsky, yet she hides her diagnosis from everyone. Her sister Brigid, a cancer survivor, becomes entangled with Rob Jacobson. When Jane calls Brigid as a surprise alibi witness, the courtroom erupts. Jacobson fakes a heart attack to stop the testimony, later revealing that admitting an affair would violate his prenuptial agreement and cost him half his fortune. Brigid’s fabricated alibi and Jacobson’s bribery shatter what remains of Jane’s trust.

The trial reaches its climax when Jane calls Claire Jacobson, cornering her into pleading the Fifth about her hotel meeting with Hennessy on the night of the murders. Jane then presents a ballistics match: the .22 caliber bullet that struck Jimmy came from the same gun used in the Gates killings—a gun that vanished from Jacobson’s lockbox. In closing arguments, she insists that the real killer is still out there. The jury returns a verdict: not guilty on all counts. Jacobson collapses sobbing, but later asks Jane a chilling question: “How many times do you think a person could get away with murder?”

Three weeks after the trial, Jane—now undergoing chemotherapy—sees Jacobson leave a bar with a young woman. She follows him to his estate and hears screams. Rushing inside, she is tackled and confronted by Jacobson and a very much alive Joe Champi. Champi forces her into her home to stage a suicide, threatening to kill everyone she loves. When Ben walks in with pizza, Champi shoots him. Jane draws a concealed Walther air pistol and fires a BB into Champi’s face, then retrieves her Glock and kills him. Ben’s breathing is labored, but he survives. The story ends with Jane and Jimmy confronting Jacobson, who insists he never killed anyone, though Champi’s dying words hint at a deeper, still-buried truth.

Ending Overview

The jury acquits Rob Jacobson, but Jane’s lingering doubt is confirmed when she follows him to a bar and to his estate, where she hears a girl’s scream.

Jacobson insists he never killed anyone, yet Champi’s final words and Jacobson’s own chilling question leave the full truth ambiguous.
