At the dawn of the 20th century, three voices rose up from Poland to proclaim an ardent message, a message powerful enough to alter the course of an age plunging into spiritual darkness.

Filmed on location in more than 20 cities across Poland and the United States, this true story examines and chronicles the phenomenal lives and spiritual legacy of Saint Faustina Kowalska, Saint Maximillian Kolbe, and Pope John Paul II, modern day "Apostles of Mercy."

Through the 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 struggle and herald the message of Divine Mercy to all mankind.
