When The Sandman, also known as Lord Morpheus, the immortal king of dreams, stories, and the imagination, is pulled from his realm and imprisoned on Earth by a nefarious cult, he languishes for decades before finally escaping. Once free, he must retrieve the three "tools" that will restore his power and help him to rebuild his dominion, which has deteriorated in his absence. As the multi-threaded story unspools, The Sandman descends into Hell to confront Lucifer, chases rogue nightmares who have escaped his realm, and crosses paths with an array of characters from DC comic books, ancient myths, and real-world history, including: Inmates of Gotham City's Arkham Asylum, Doctor Destiny, the muse Calliope, the three Fates, William Shakespeare, and many more.
