This is a preview of the series White Smoke.

"White Smoke, Episode 13: Ratlines" examines the troubling post-World War II period when certain Vatican officials helped Nazi war criminals escape justice. The episode focuses on key figures like Bishop Alois Hudal and Croatian priest Krunoslav Draganović, who provided fugitives including Adolf Eichmann, Josef Mengele, and Klaus Barbie with false documents and escape routes to South America.

Their motivations ranged from ideological sympathy to anti-communism. While not official Vatican policy, these "ratlines" operated within Church networks and resources. The episode explores how elements within an institution founded on moral principles became entangled in activities that contradicted its own teachings and obstructed justice.
