On the eve of the 5th of November, Catesby, Fawkes and the plotters load the tunnels below Parliament with barrels of gunpowder. Across the city, Father Garnet is under pressure to reveal Catesby's plot for the good of the Catholic faith. Will the priest be the one to betray Catesby at the eleventh hour?
Following the death of Elizabeth I, King James of Scotland claims the English throne, and the country goes to war with Catholic Spain. As a result, English Catholics are persecuted and driven into hiding, but after witnessing the brutal means by which the Crown intends to punish his people for practicing their faith, recusant Catholic Robert Catesby devises a treasonous plot to assassinate King James. However, he must first enlist the aid of stalwart allies, and heads to Brussels to seek the help of a hardened war veteran named Guy Fawkes.
