The Twelve is a gripping courtroom drama that tells the unique stories of 12 ordinary Australians who are part of the jury in a disturbing murder trial where Kate Lawson (Kate Mulvany) has been accused of killing her teenage niece.

Behind their anonymous exteriors, the jurors hide dark stories — from shameful secrets and shattered dreams to personal trauma and glimmering hope. 

As we delve into the jurors personal histories, the viewers will discover the tumultuous and flawed way we try to determine justice in our society, as the individuals bring their prejudices to the court room.

Based on the 2019 Belgian series, De Twaalf, The Twelve has won a number of awards in Australia since being broadcast on Fox Showcase.

With a star-studded cast at the helm of this Australian series, let's see who is part of the cast for The Twelve, which will air on ITV1...
