The charismatic Father Fromenger welcomes the new students.

After a student gets attacked by a drug addict he was trying to help, repercussions ripple through the seminary.

The investigation led by the Vatican representatives of the Capuchin seminary puts Father Fromenger and Father Bosco, his right arm, into a painful case of conscience. The seminarists, who are ready to live their very first confession as future priests, must stand up for their faith.

For Christmas celebrations, Yann, Raphaël, Emmanuel, Guillaume and José are sent for an internship in a small village where a conflict between a local priest and his community adds complications to their journey. As for the Capuchins, Father Bosco decides to secretly travel to Rome to save Father Fromenger’s head.

The seminarians skirmish with the police as they try to help a group of illegal African immigrants facing eviction.

Following his brother’s tragic death, Raphaël forsakes his friends who are now deep inside their doubts about their involvement in the homeless case. In the Vatican, a diplomatic conflict with China calls into question the measures of punishment taken against Father Fromenger.
