On October 31st, 1517, a lone German monk struck a hammer blow that would shatter the religious unity of Europe and inadvertently give birth to the modern world. From that single spark in Wittenberg, the history of Protestant Christianity is an epic narrative of courage, theological rediscovery, and radical societal shift.

It is the story of everyday people gaining access to the scriptures in their own languages, sparking a revolution in literacy and individual conscience. Moving from the initial protests of Martin Luther and John Calvin to the massive global missionary movements and the diverse denominations of today, this documentary traces a faith defined by ongoing reform. This is not a dramatized legend. This is the historically accurate, chronological timeline of the Protestant movement. This is the story of Protestantism.
