In April 1967, the office of Marvin Kramer, a Jewish civil rights lawyer in Indianola, Mississippi, is bombed by the Ku Klux Klan. The attack kills Kramer's five-year-old twin sons and leaves him gravely injured, ultimately leading to the amputation of his legs and his later suicide. The Klansman responsible, Sam Cayhall, is tried for murder in the bombing and is eventually convicted and sentenced to die in the gas chamber at the Mississippi State Penitentiary. Twenty-nine years pass before a new chapter begins.
Adam Hall, a young attorney at the Chicago firm Kravitz and Bane, is assigned to take on Cayhall’s case as a pro bono matter in the weeks leading up to Cayhall’s scheduled execution. He is Cayhall’s grandson, part of a family that has moved away from the South and changed their name to escape the weight of the past. Adam is driven by a desire to understand the dark legacy that shaped his father’s life and his own, including the circumstances surrounding his father’s suicide, which Adam recalls from his childhood when he found his body. As Adam travels to the South for the case, he reencounters his aunt, Lee Bowen, a glamorous but alcoholic socialite who has managed to keep her tie to the family quiet. She cautions him about digging too deep into a past that might ruin what remains of their lives.
On death row, [Sam Cayhall] is a blunt, bitter, and unapologetic racist who repeatedly boasts about his role in the Klan bombing campaign, though he denies that the incidents were meant to kill. He agrees to let Adam represent him, but he forbids any clemency requests to Governor McAllister, who had prosecuted him in a prior retrial and built his political career on that case. Yet the Governor’s aide, Nora Stark, approaches Adam with a contrary possibility: clemency could be possible if Cayhall would reveal information about unidentified co-conspirators. This twist nudges Adam into a broader investigation of the bombing’s origins and its possible connections to a wider network.
As Adam digs, inconsistencies surface. The facts of the original case appear muddier than Cayhall would admit, suggesting he may not have acted alone or with sole responsibility for the bomb. Stark and a former FBI agent hint at a broader conspiracy involving the Mississippi State Sovereignty Commission and White Citizens’ Councils, organizations active at the time in opposing civil rights progress. Cayhall himself resists accessing the Sovereignty Commission’s sealed files, fearing exposure of former allies in the Klan and fearing the Governor’s true motive—political leverage rather than justice.
Meanwhile, Adam presses forward with legal maneuvers—motions for stays of execution and arguments that Cayhall may be legally insane due to indoctrination into the Ku Klux Klan, arguing that his client’s ability to distinguish right from wrong could be compromised. In parallel, Lee confronts her own past. She reveals that in the early 1950s, as children, she and Adam’s father witnessed Eddie, their brother, murder their Black neighbor Joe Lincoln after a dispute over a toy soldier. Eddie’s guilt, and Lee’s failure to intervene, contribute to his later suicide and to her own spiraling alcoholism. They also share a historical photograph showing Sam Cayhall as a boy at a lynching, a vivid reminder of the family’s long-tangled history.
Adam and Nora secretly gain access to the Sovereignty Commission’s files, which illuminate a wider conspiracy and indicate the participation of an accomplice. A former FBI agent reappears to tell Adam that the FBI had identified Rollie Wedge, the accomplice the agency could not convict, who now reunites with other Klan members to mark the bombing on the eve of Cayhall’s execution. Adam attends a Klan reunion, where he is assaulted and threatened at gunpoint by Wedge. The confrontation intensifies as the truth about Sam’s hatred and its devastating impact on his family emerges, and Sam begins to soften, mending fences with Lee and expressing remorse for the damage his actions caused. He nonetheless rejects Wedge’s attempts to push him toward silence, and it becomes clear that Wedge built and timed the bomb.
Despite Adam’s perseverance, the courts—including the United States Supreme Court—deny the stay of execution. Even though Cayhall eventually authorizes the release of the Sovereignty Commission files, Governor McAllister refuses clemency, turning the files into political leverage as Cayhall had feared. Rollie Wedge is eventually identified and arrested as a consequence of the newly uncovered evidence.
In the end, [Sam Cayhall] is executed in the gas chamber. Adam remains a steadfast advocate for his grandfather until the last moment, and he and Lee share a quiet embrace, holding out hope that the ghosts of the past might fade, even as the system’s final decision underscores how deeply history and personal guilt can collide, shaping a family across generations. The case closes with a somber reminder of the costs of bigotry and the long shadow it casts over those entangled in its wake.
