God Willing (2015)

Tommaso is a successful, respected cardiac surgeon who also happens to be arrogant and an atheist. However, Tommaso’s only son Andrea brings the family together to announce that he wants to become a priest. Tommaso refuses to accept his Catholicism, and is horrified when his wife Carla and daughter Bianca consider it themselves.

Tommaso goes undercover while Andrea is absent, on retreat in a monastery, to investigate and bring down the charismatic Father Don Pietro, who he believes has “brain-washed” his son and caused upheaval in his family.
