Set to air on BBC One, Gunpowder is a historical thriller that relates to the narrative of the well-known Gunpowder Plot, which is a 17th-century conspiracy plot to blow up the British House of Lords in an effort to assassinate King James I. The event still holds a special place in British history which is why up until now, it is commemorated every November 5 in Britain as Guy Fawkes Day – named after one of its main conspirators.
