The transition has been bumpy. He loves teaching history to inner city teens, but he hits a roadblock when a belligerent student, Colton, possibly a white-supremacist, behaves in ways that threaten Niall. As troubles mount at school, Niall's girlfriend Lluvia pressures him into make a deeper commitment to their relationship. She wants them to move in together with Lluvia's pre-teen daughter and elderly mother. Haunted by his failure as a Cistercian monk and his troubles with one man in particular, the abusive Brother Thomas, Niall abandons Lluvia and heads back to his old monastery in Massachusetts for a final showdown with Thomas, now dying of ALS. Redemption for Niall is elusive as he strives to mend his faith.
