Jung In-hoo, a master of legal battles, takes on one of the most challenging political trials in South Korean history by defending Park Tae-ju, the chief secretary of the intelligence agency implicated in the assassination of the president. Despite the overwhelming odds, with Tae-ju's sentence seemingly predetermined due to his military status, In-hoo fights relentlessly to ensure a fair trial. However, his frustration boils over as he faces an increasingly unjust legal process.Thirty minutes before the assassination, Tae-ju receives an order from the chief of the intelligence agency to subdue the bodyguards if necessary. The central issue in court becomes whether his actions were a "premeditated act of rebellion" or "obedience to orders under duress". Although In-hoo advises Tae-ju to testify in a way that could save him, Tae-ju remains steadfast, refusing to betray the trust placed in him.Meanwhile, Jeon Sang-doo, the ambitious leader of the joint investigation team, harbors dangerous ambitions following the events of October 26. He manipulates the trial from the shadows, eavesdropping on proceedings and subtly steering the outcome by sending real-time notes to the court, all while mocking the determined In-hoo.
