4/20 is coming up, so this episode is dedicated to illicit substances. Sheena covers legendary Appalachian bootlegger Mahala Mullins. Hannah takes us to Mexico to explore Jardines del Humaya, a cemetery full of drug cartel members' opulent mausoleums. She also covers drug dealer Adolfo Constanzo and the murder of Mark Kilroy (trigger warning: this story is especially graphic). Lori covers bootlegger Willie Carter Sharpe and the "King of Bootleggers" George Remus.
