Black Mirror

Are computers now so sophisticated that they can believably emulate a real human being? So sophisticated that a computer can react and talk like them - after death?

Martha (Hayley Atwell) and Ash (Domhnall Gleeson) are a young couple who move to a remote cottage, where Ash's parents used to live. Ash is a big user of social media, tapping away on his phone, just a bit too much. Martha doesn't really mind, she loves him and they're looking forward to their new life together. The day after the move, Ash is killed, returning the hire van.

At the funeral, Sarah (Sinead Matthews), a friend of Martha's, tells her about a new service that lets you stay in touch with the deceased. By using all his past online communications and social media profiles, a new 'Ash' can be created - disarmingly 'real' and a help to a grieving partner. Martha is disgusted by the concept and wants nothing to do with it.

Martha decides to stay in the cottage, despite her sister, Naomi (Claire Keelen), being worried about her isolation. Then one morning Martha receives an email from 'Ash'. Sarah has signed her up. Martha is furious and deletes the message.

But then she discovers she is pregnant and in a confused and lonely state Martha decides to talk to 'him'.
