Tess and Sunny pursue a killer who uses an untraceable ghost gun to take down powerful victims with no discernable connection to each other. As the threat of a spree killer looms over Metro PD, Leo asks for Tess's support to investigate the anonymity of digital worlds where dark alliances and online fantasies have real life consequences. With Matt's help, Tess and Sunny work against the clock to dissect perfect alibis and expose the killer before another life is taken. Meanwhile, Sunny gets carried away in her healing journey.
