Roger, a struggling Asian-American man living on the streets of Seattle, wakes up to find his life has taken a turn for the bizarre. After losing his supermarket to local crime and falling into deep debt, he is thrust into a harsh reality of homelessness. However, his misfortune is compounded by the sudden awakening of a 'Cthulhu System' that insists on treating his gritty, modern-day struggle as a cosmic horror investigation.

As Roger navigates the dangerous, desperate world of the homeless, he must balance his dwindling sanity with the system's cryptic demands. With his SAN value plummeting and strange, supernatural occurrences manifesting in the shadows of the city, Roger must learn to survive, secure 'Anchor Points' among the city's outcasts, and uncover the dark secrets lurking in the fog of Seattle—all while trying to earn enough money for his next meal.
