After learning about a new service that lets people stay in touch with the deceased, a lonely, grieving Martha reconnects with her late lover.
Martha is devastated when her partner Ash is killed in a road accident on the day they planned to move to a country cottage. At Ash's funeral, Martha's friend Sarah tells her of a new service which allows people to communicate with their deceased loved ones by using all their online communications and contributions. Martha is appalled, and decides to stay in the cottage despite her sister's view she is isolating herself. One day Martha gets a message from Ash, and she realises Sarah has signed her up for the service. Initially, Martha's displeased but, on finding she's pregnant, relents and relishes their conversations. With her comfort-level growing talking with the synthetic Ash, it isn't long before 'he' tells Martha about a 'next level' of communicating - one which is...experimental.
