After closing Ada's case, Gavin and Nines return to normal life with the addition of their new relationship. However, love alone can't change Gavin Reed. It can't erase the struggles of his past or his hostile temperament, and his relationship with Nines pays the price. Following yet another argument late at night, Gavin storms out of the precinct alone. He doesn't return to work in the morning, and a haunting clue suggests there may be more to Gavin's disappearance than a temper tantrum. When a mysterious person contacts Nines and reveals they have taken Gavin hostage, Nines is given a choice: kill Markus, so Gavin's captor can take his place and lead androids to supremacy above all beings, or find Gavin's body in the Detroit River. Faced with the impossible decision of choosing between the man he loves and the man who gave him his freedom, Nines is determined to find another way. However, if he fails to find a solution soon enough, his decision might just be made for him.
