At the dawn of the twentieth century, three voices rose up from Poland to proclaim an urgent message, a message powerful enough to alter the course of an age plunging into spiritual darkness.

Filmed on location in more than twenty cities across Poland and the United States, this true story examines and chronicles the phenomenal lives and spiritual legacy of St. Faustina Kowalska, St. Maximilian Kolbe, and Pope St. John Paul II, modern day "Apostles of Mercy."

Through never before seen film footage, rare photographs, and extensive interviews with friends, biographers, and family members, this story journeys across a dramatic visual landscape to document their heroic struggles and herald the message of Divine Mercy to all mankind.
