On Christmas Eve in 1966, Philip Potter, a kind-hearted Smithsonian curator, wraps up his last-minute shopping. Meanwhile, James, his lover of several years, takes his own life back in their home. Unaware of what awaits him, Philip drops off gifts at a homeless shelter, an act of generosity that will later make him a suspect in the murder of a male prostitute.
Following James’s shocking death, two men enter Philip's life—and both drive yellow Continentals. One of them, though, is a killer, with the blood of at least six hustlers on his hands. And both are hiding something.
As Philip is about to discover, no good deed goes unpunished.
