When his desperation for sleep drives colorblind Ryan Savage, an insomniac artist from Las Vegas, to take a potent cocktail of sleeping pills, drugs, and other unknowns, he falls down a technicolor rabbit hole and lands in the world of grim reapers, muses, and oracles. Determined to stay in the world of colors so long lost to him, he quickly takes up an apprenticeship beneath Bishop, the leading grim reaper of the realm. Secured in his new world and vocation, Savage is soon helping Bishop track a serial killer across the US, with each killing an eerie echo of the violent art from Savage's own mind. In order to catch the killer before he strikes again, Savage must revisit his past, his beliefs, his memories, and the pieces that have been left to exile.
