A Catholic parish is torn apart when two of its members are accused of murder

The year 1806 is not a good time to be Catholic in Boston. When a man is brutally killed on the Boston Post Road, two unsuspecting Irishmen are charged with the crime. For five months they rot in prison, denied a lawyer until just two days before the hearing. It is a mockery of justice—a one-day trial that results in a unanimous verdict: The Irishmen will be hanged, dissected, and dismembered.

Comforting them falls to Father Cheverus, a French émigré struggling to adapt to life in the New World. It is his duty to help the condemned find peace, but any overture he makes to the prisoners will be met with an anti-Catholic backlash that could destroy his fledgling congregation. As he walks a fraught path, the priest must decide: Is his obligation to his flock, or to God?
