Following the passing 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.
