Season 4 of this historical crime drama opens on Jan. 1, 1985, where Ronald Reagan successfully has won re-election to the presidency. Yet while this president declares that it's "morning again in America," the demand for crack cocaine on the streets of South Central Los Angeles remains higher than ever. Franklin Saint (Damson Idris) and his dealers are reaping the benefits of this rise in drug addiction, but the Los Angeles Police Department is diverting unprecedented money and resources to Washington's new "war on drugs." Another episode follows.
