Based on James Ellroy's "Blood's A Rover," which is officially described as follows: "Martin Luther King assassinated. Robert Kennedy assassinated. Los Angeles, 1968. Conspiracies theories are taking hold. On the horizon looms the Democratic Convention in Chicago and constant gun fire peppers south L.A. Violence, greed, and grime, are replacing free-love and everybody from Howard Hughes, Richard Nixon and J. Edgar Hoover to the right-wing assassins and left-wing revolutionaries are getting dirty. At the center of it all is a triumvirate: the president’s strong-arm goon, an ex-cop and heroine runner, and a private eye whose quarry is so dangerous she could set off the whole powder keg."
