While searching for an escaped nightmare in the waking world, Morpheus falls prey to Roderick Burgess, an occultist looking to summon and imprison Death.

Morpheus begins his quest to find his tools of power — his sand, ruby and helm — by paying a visit to a pair of notoriously dysfunctional brothers.

When a gathering of the Endless exposes deep-seated grievances, Morpheus embarks on a mission to Hell to free the soul of a condemned mortal.
