A sleep-deprived Sunny has the day off, as Tess gets pulled into a 911 call with an injured man locked in a steel drum who has no idea who, or where, he is. As Tess navigates motives of revenge and a business rivalry in a race against time to uncover the location of the victim, Sunny takes drastic actions to maintain her fragile sense of safety, convinced she witnessed a murder on her building's CCTV cameras. As the case culminates in a dramatic end, Tess struggles with revealing her own hidden truths to rescue the victim. 

Tess is forced to revisit her legally blind diagnosis when a lawyer leverages her vision loss as grounds to open a case involving her eyewitness testimony, which could put the case and her consulting role with the police at risk. When Bennett and the rest of the department keep Tess at arms' length, she begrudgingly accepts the help of new detective Owen Cooper to solve the case a second time. In an attempt to work through the mounting pressure, Sunny begins sessions with her new therapist.
