When an income tax officer makes him an offer he can't refuse, Easy Rawlins is forced out of retirement and into the infiltration of his local church, the First African Baptist, and the surveillance of local radicals. The murderers strike and he becomes the prime suspect of the Los Angeles Police Department who lose no sleep over the fate of 'freelance' private eyes.
