As Jacob uncovers the mystery of Stephen's past, he realizes his mentor was embroiled in a plot far more sacrilegious than he originally thought. The scheme of his mentor's death pulls him deeper into the church, bringing him closer to the elusive figure at the head of the Trinity. But once Jacob realizes his role in the Order's machinations, it is too late for him to disentangle his truth from its heresy. A sacrilegious Order, a murdered priest, and a vault of secrets converge to make up "The Trinity."
