They use necromantic arts to resurrect Macbeth, and he soon embarks on a wild killing spree, turning most of the Scottish court into zombies and raising the corpse of his wife (Laura Maitland) along the way.

Macbeth (Craig Annis) has been slain by Macduff (Grant Foulkes). When the newly crowned Malcolm (Ben Ewing) refuses to grant the tyrant a Christian burial, it plays into the hands of Hecate (Pieta Farrell) and her witches (Shireen Morris, Brooke Antulov, Erin Oliver).

When the cowardly Fleance (Michael Finney) assumes the throne, it seems that Scotland's only hope lies with Macduff, who must quest into the maw of hell itself to stop an undead scourge laying waste to the country.

Remarkably, Mence has written the play in iambic pentameter. He has a flair for it. While there's a lot of groanworthy Shakespearean parody, there's just as much clever pastiche and occasionally, the sort of vivid and inventive homage that could sustain a scholarly hoax.

Then there are the zombies. With ghoulish make-up, bits of offal and fake blood, the actors come into their own as the play descends into a schlocky gorefest (much of it inspired by Sam Raimi's Evil Dead movies - Macbeth even chops off his own hand and attaches a chainsaw to the stump).
