A discovery in the house leads Thomas to go down memory lane, but as Alison comes to realise, memory and reality don't always go hand in hand, especially when there are ghostly witnesses eager to tell their own version of events. Meanwhile, Mike struggles with his own distorted memories of Alison's past and dreads confronting an old adversary.
