It's the year 2446, and the final horseman of apocalypse - Death - is preparing to ride.

The Archangel of Mercy, Tzadkiel, has come to Earth and found the last merciful person among the callous human throng. Together, Tzadkiel and Lourdes escape to the French countryside, but are relentlessly tracked by a sadistic officer determined to control the Archangel and claim Lourdes for himself.

Forced to make choices neither ever anticipated, they discover more than simply how to survive. Yet while love blossoms, Death grows impatient. Unable to ride until released by the Archangel, he unleashes a calamity that will push them to their very limits. To succeed they will need more than hope and love.

They will need a place of mercy.
