Maggie takes on the responsibility of Assistant Crown Prosecutor in the high-profile murder trial of a Filipino woman charged with the brutal murder of her husband, a "good charitable bloke" who portrayed Santa every year at the RSL. The case seems like an open-and-shut win for the prosecution - but is it? The case takes an unexpected turn when a juror jumps to the defence of the accused, suggesting the woman must have been acting in self defence against her abusive husband, a man she alleges killed his first wife, a crime for which the juror's fiancé was convicted. As the trial proceeds, the Heelers investigate the juror's claims and slowly begin to uncover the man's history of abusive behaviour towards women. The outcome of the case hinges on the emotional testimony of the only person who truly knows what happened, the accused.
