In 1986, an unassuming Cleveland grandfather and autoworker is accused of being Ivan the Terrible, a brutal Nazi death camp guard.

As survivors of the Treblinka death camp take the stand against John Demjanjuk, his lawyers seek ways to challenge the accuracy of their testimony.

The authenticity of an ID card is questioned, Demjanjuk shifts his legal strategy, and the defense hears of evidence found in a McDonald's dumpster.

Demjanjuk testifies in his defense, but his alibi raises questions. Later, the fall of the Berlin Wall may lead to a trove of KGB evidence.

Tensions run high in Israel and around the world as Demjanjuk's trial comes to a conclusion. But even that's not the end of the story.
