London, 2029. Detective Inspector Neil Nowak is investigating the case of three missing people. He discovers that each person in question had an identical, strange digital recorder, locked in a black box and hidden in their homes, each with over an hour of recording.

The recordings give an insight into the lives of three people struck by tragedy, and how they struggle to deal with it. What they don’t provide, however, is the answer to the question: what has happened to them? The only clue the detective has is the inscription on the black boxes - How Copy.
