A 17-year-old girl faces a murder trial after allegedly stabbing her friend’s boyfriend, resulting in his death. The prosecution charges her with murder, while she claims the act was in self-defense. During deliberations, twelve jurors are secluded in a jury room with just two hours and twenty minutes to reach a unanimous decision. What initially appears to be a straightforward case quickly turns intricate when one juror voices concerns, prompting the entire jury to scrutinize the evidence more closely, challenge their initial beliefs, and confront their own biases.
