As we catch our breath over the holidays, enjoy this episode of Slate's One Year podcast. What Next returns next week.

In 1942, federal officials targeted a group of Black Americans who were allegedly hoping for a Japanese invasion. They uncovered a plot that included stockpiles of weapons and secret passwords—but was any of it true? This week, Joel Anderson tells the story of a shadowy organization in East St. Louis, Illinois, the group’s mysterious leader, and an alleged conspiracy against America during World War II.

This episode of One Year was produced by Evan Chung, Sophie Summergrad, Sam Kim, Joel Anderson, Sol Werthan, and Josh Levin.

Derek John is executive producer of narrative podcasts and Merritt Jacob is senior technical director.
