When an activist priest meets a grisly death in his own cathedral, the crime has all the hallmarks of a routine Bangkok Park gang killing. The perp is a demented ex-FBI agent named Speer in search of the infamous O´Zebedee brothers who have been hijacking local radio airwaves with their subversive diatribe. Detective Hannah Shaw tracks Speer´s enraged quest to Wireless, the retro-radio nightclub and epicentre of a diverse subculture. She must stop the defrocked Fed or fall prey to a campaign of censorship, violence and ultimately death.
