Martha allows herself to believe that she is talking to her dead partner, and over the following weeks, she talks to the artificial Ash almost non-stop, keeping him updated regarding the pregnancy. She then uploads videos and photos of Ash to the service's database, and the service duplicates Ash's voice to talk to Martha over the phone. She starts to communicate with him through instant messaging and informs him of the pregnancy. Becoming emotionally unstable, she responds to the artificial Ash's e-mail. Over the following days, Martha is overwhelmed by grief and soon discovers that she is pregnant. When Martha gets an e-mail supposedly from "Ash", she furiously confronts Sara, who urges her to at least give the service a try before dismissing it.

Martha rejects the idea outright, but Sara signs Martha up to the service anyway, without telling her. By using all of his past online communications and social media profiles, a new "Ash" can be created virtually. At the funeral, Martha's friend Sara (Sinead Matthews) tells her about a new online service that lets people stay in touch with the deceased. The day after moving into the house, Ash is killed returning the hire van. Ash is a social media addict and compulsively checks his phone for updates on his social network pages. Martha (Hayley Atwell) and Ash (Domhnall Gleeson) are a young couple who move to a remote house in the countryside.

It was written by Charlie Brooker, and was released on February 1, 2013. Be Right Back is the first episode of the second season.
