Preach Modern shows a documentary team following Damien, an eager and charming student, to document his way into priesthood as a young adult. It quickly becomes clear that Damien has no idea about celibacy and to make matters worse, he is very popular among his female classmates.  Throughout the documentary, Damien and his mentor, Father Titus, work towards a trial service that young Damien will hold at Father Titus' local church. On their way to promote the trial service and Catholicism, Titus encounters memories of his past as a young priest, and Damien must confront his female classmates, who are helplessly drawn to his charms. Will Damien be able to resist accidental temptation or is he in for an unexpected shock?
