Police officer Peggy Whitfield receives a series of social media messages that instruct her to commit murder or she herself could be killed. As she investigates the mysterious messages, Peggy learns of a computer program named Clean that uses online activity to target those deemed unworthy. The ramifications of the program become clear as the bodies pile up, and Peggy questions the motives of those closest to her. When she decides to fake her own death, is it a brilliant plan that will thwart Clean? Or has she made it easier for someone to kill her without facing the consequences?

Clean tackles head-on one of current society's biggest fears: what happens when we use a computer to make decisions, and the computer starts making decisions by itself?
