As the jury is selected for Kate Lawson's lengthy trial, the press follows the sensational case of her missing 14-year-old niece, Claire Spears, who is presumed murdered. When the jurors meet for the first time, it's clear this is a diverse group, who bring their own problems to the table. Georgina, a middle-class mum, is caught between her duty to the Court and her duty to her family. Garry, a gambler struggling with debt, learns the history of fellow-juror Corrie.

The Crown calls Detective Sam Chedid to the stand. Various pieces of evidence are introduced to the Court, including a disturbing video of Claire. During his cross examination, Colby throws suspicion onto Nathan Spears, as he points out the Detective's failure to investigate him as a potential suspect. The jurors share polarizing opinions on the trial thus far, as different personalities begin to rub each other the wrong way.

The Crown calls Claire's best friend, Amita, to the stand for questioning. Bloom suggests Kate was grooming Claire while using her as her muse, but Colby's cross examination paints Kate as a loving and caring Aunt. The Defence again throws suspicion onto Nathan, as it's revealed a dramatic argument took place the night Claire went missing. Meanwhile, Jarrod struggles to deal with the brutality of his arrest and submits an important English essay late.

As Kate's artwork is put before the Court, Bloom focuses on its preoccupation with mortality and suggests Kate orchestrated Claire's death for her final work. A complicated mental health diagnosis is revealed, which is particularly pertinent for Vanessa. The jury room is once again divided as they begin to untangle the mammoth question in front of them.

Claire's father is called to the stand. Nathan paints Kate as a sexual predator, who groomed Claire before murdering her. However, Colby throws suspicion back onto Nathan when it's revealed he had a false online persona, posing as a young girl in order to monitor Claire's social media. The courtroom is also given a taste of his temper when Colby successfully gets under his skin.

When the jurors are taken to Kate's house to observe a demonstration of the Crown's theory, it ends in disaster for the Defence when someone tampers with Kate's studio. Back in the courtroom, an eyewitness testifies he saw Kate at 4am out on the water the night Claire disappeared. Kate's brother, Robbie, takes the stand, before the jurors are left perplexed when a man from Kate's past causes a disturbance in the courtroom.
