Set in Kansas City in 1933, Eastwood plays a police lieutenant known simply by his last name, Speer. Reynolds plays a former cop turned private eye named Mike Murphy. Both Speer and Murphy served on the force together and were once good friends, but are now bitter enemies. When Murphy's partner is slain they team up again to fight the mob.
In smoggy 1970s Los Angeles, Jackson Healy (muscle-for-hire, recovering alcoholic) and Holland March (private eye, practicing alcoholic) are brought together by the suicide of a fading porn star. Problem is, the dead girl's aunt is convinced she saw her niece alive and well, after the highly publicized incident. March needs money, takes the case, and within days, it's blossomed into a far-reaching murder conspiracy, bizarrely rooted in smog and the U.S. auto industry.
