A serial killer is on the loose in Metropolis, and Clark always seems to be one step behind him, while Chloe's paramedic friend seems to think he blacks out and performs the dirty deeds, himself.

Davis asks Chloe if she can go away from the city with him, but when Clark realizes Davis is alive, he confronts Chloe to give him an explanation about it. Meanwhile, Oliver discovers that Jimmy has become a pill-popping junkie and offers his services and emotional support. But Jimmy is too consumed by his anger and paranoia and brushes off Oliver. Later, when Oliver sees Jimmy breaking into Chloe's apartment to steal money and items to buy more drugs, things get worse when Davis appears and attacks them both. It leads to an angry Clark tracking down Davis/Doomsday to the ruins of the Fortress of Solitude for a brutal confrontation.
