When the body of social worker Kera Jacobsen shows up on Chief New York City Medical Examiner Laurie Montgomery's autopsy table, it appears she was the victim of a drug overdose. But Kera's family and friends swear she never touched drugs. And although Kera was 10 weeks pregnant, nobody knows who the father was --- or what he might know about Kera's final moments alive. With Laurie temporarily sidelined by a medical emergency, her new pathology resident, Dr. Aria Nichols, turns to a controversial new technique: collaborating with experts at a start-up ancestry website to trace the fetus's DNA in the hopes of identifying the mystery father. But when Kera's fellow social worker is murdered, it becomes clear that someone doesn't want Kera's secrets to come to light.
