This episode is brought to you by Wondery in partnership with National Geographic in anticipation of their new series, The Hot Zone. The three-night limited series is inspired by true events surrounding the origins of the Ebola virus and its arrival on US soil in 1989. That year, the killer virus suddenly appeared in monkeys in a scientific research lab in the suburbs of Washington, D.C. Lieutenant Colonel Nancy Jaax, a heroic U.S. Army scientist, puts her life on the line to head off the outbreak before it spreads to the human population.

In this episode, Julianna Margulies, the Golden Globe and Emmy award winning actor, shares what it was like to play Dr. Nancy Jaax and why she thinks it's important to tell the stories of epidemics — and the people on the front lines who fight them. We’re also joined by Brian Peterson and Kelly Souders, executive producers and showrunners of The Hot Zone.
