Fillydelphia has long held a reputation as a cesspool of crime and degeneration, where drugs run rampant, gangs fight in the streets, and death is a daily occurrence. Amongst so many victims, the murder of White Rose might have been overlooked had it not been for one thing; she is the mother of Flash Sentry.

Upon learning of her death, Flash returns to his hometown to solve her murder and catch those responsible, aided by Twilight Sparkle, Spike, and Phillip Finder. But upon arriving at Fillydelphia, they quickly learn that crime may be the least of the city's problems; a militaristic Guard, uncaring leaders, and an apathetic populace have formed a web of corruption that entangles the city.

White Rose's death may be the key to changing everything. But what chance do four outsiders have against an entire city?
