This Gimlet Media show has an incredible cast—Catherine Keener, Oscar Isaac, and David Schwimmer, to name just a few regulars. It deals with the ethical quandaries of a woman helping to oversee a government medical experiment, and the format does a great job of toying with narrator reliability. Are the people you're hearing well-intentioned, or are they lying to themselves and one another? Do they even remember the events they're supposed to be guiding us through? The show led to a TV series, which is something we can expect from more and more of our favorite audio dramas. Listen now!
