John Denstoff, a police officer investigating the vanishing employees of the Veil Corporation in Ashmoor, uncovers a sinister plot by the company's CEO Vekroff to weaponize a supernatural black mist that warps people into savage creatures. The scheme hinges on deliberately spreading the infection across the city so that Vekroff can monopolize the antidote market and reap enormous profits. When John himself falls victim to the transformative mist, he joins forces with Lidia Winchester, a dedicated researcher, to track down a means of reversing the infection before the company's malevolent gambit consumes everyone around them.
