Joy Stapleton is Irelandâs most infamous prisoner. She was incarcerated for two life sentences after the bodies of her two young sons were found buried in a shallow grave in the Dublin mountains. But she has always maintained her innocence and argues the only reason she was ever arrested in the first place comes down to mere coincidence. But itâs a coincidence that didnât convince detectives, that didnât convince a jury, and that hasnât endeared her to the inmates of Mountjoy Prison. That is until eight years into her sentence, when new evidence emerges, and everybodyâincluding Joyâs long-suffering husbandâis forced into a rethink. Take your seat in the courtroom for the retrial of the century...and see just how wide youâre willing to allow a coincidence to stretch your beliefs.
