For the first time ever, we examine the fairness of the system, and the inner workings of justice in the UK. Filmed over ten days, a real murder trial is recreated word-for-word from the original transcripts, and two randomly-chosen juries, neither of whom are aware of the other, are asked to judge. The case? A man who admits he killed his wife, but whose defence maintains that he lost control, and is therefore not guilty of murder. What will the two juries decide, and why?
