Eve's been struggling since her retirement. Cancelling appointments, forgetting simple things…sleeping an awful lot. Her three kids are worried. When the oldest decides to check in on Eve before heading off to an important work dinner, the simple visit turns into something much bigger, and darker, than anyone could have predicted. Through found audio - phone calls, Facetime, Skype, live social media posts and recordings caught by unwitting bystanders - listen in as Abi, Kay and Joey work with, and sometimes against, each other as they try to piece together what happened…and who's to blame.
