Sick launches its first season by exploring the widely reported case of Donald Cline, an Indianapolis fertility doctor who used his own sperm instead of a donor’s to inseminate patients. Until they stumbled on the truth through at-home DNA testing, none of the patients he worked with were aware that he had fathered their children, nor were those children aware of their parentage. Yet what Cline did wasn’t technically against the law. The hosts and health reporters Jake Harper and Lauren Bavis explain the facts of the case, but what Sick does best is to give voice to the people affected by Cline’s gross breach of trust, including former patients who feel violated and their grown children who are now struggling to make sense of their identity. Sick plays out a series of unthinkable what-ifs that will leave audiences riveted, outraged, and eager to hear more.
