When the trail goes cold on a string of robberies, Detective Janet Vertran is forced to call on her ex Fiona for help. When Fiona broke things off between them two years earlier, Janet swore she'd keep her distance. But she also knows from past experience how helpful Fiona's creation, an android named Pat, can be in ferreting out the little details that make all the difference when solving tough crimes.
Though the robberies appear to have been conducted by separate individuals, Pat finds an unexpected connection between them. But as Janet, Fiona, and Pat get closer to unearthing the truth, it becomes clear the case is taking an emotional toll on Fiona.
As she works with her ex once again, Janet is reminded of old times and familiar feelings begin to stir. Is it possible they'll get a second chance to make their relationship work? And will Janet find the courage to do what it takes to find out?
