In this Derek Jarman version of Christopher Marlowe's Elizabethan drama, in modern costumes and settings, Plantagenet king Edward II hands the power-craving nobility the perfect excuse by taking as lover besides his diplomatic wife, the French princess Isabel, not an acceptable lady at court but the ambitious Piers Gaveston, who uses his favor in bed even to wield political influence - the stage is set for a palace revolt which sends the gay pair from the throne to a terminal torture dungeon.
