The Flash hunts down his wife's murderer!
Central City is in the grip of fear. A vigilante mob, hunting for deranged murderer, Clive Yorkin, corners a man in Central Cty Park. The vigilante mob opens fire, only to have the Flash rescue the man, at the last second, revealing him to be an innocent transient. The sober realization that they nearly executed an innocent man disperses the vigilante mob. A police helicopter gets a spotlight on Yorkin. The helicopter is attacked by Yorkin, who uses his strange power to fill the officers with fear, before draining away their life essences. Stray gunfire takes out the helicopter's rotors, causing it to crash. Yorkin is the only survivor.
Responding to radio calls, police are quick to surround Yorkin, but the brutish killer vaults a wall and escapes. Yorkin, though, has not escaped Melanie, a teenage girl with psychic powers, who is tracking Yorkin through a glass fragment, containing his psychic imprint. The Flash, as police forensics scientist, Barry Allen, returns to police headquarters. After a brief meeting with the police chief, Harvey Paulson, Allen does some background research on Yorkin. Allen turns up eleven prior addresses for Yorkin, and checks them all out, as the Flash. Melanie tracks Yorkin to a condemned neighborhood, dotted with sinkholes. Yorkin appears, quickly grabbing Melanie.
As Yorkin fills the girl with fear, Melanie finds she is unable to concentrate on her psychic bond with the Flash, and thus is unable to summon him to her aid. Nonetheless, the Flash arrives, checking on the last address on his list of Yorkin's prior residences. In a panic, Melanie broadcasts her own terror into the Flash, through their psychic link. Trying to keep his distance, the Flash attacks Yorkin with a long board. When Yorkin snaps the board, the Flash switches tactics, and pelts Yorkin with rocks. Unfortunately, Melanie gets in the line of fire, forcing the Flash to block his own attack. The impact of the rocks on the Flash's body hurls him into Yorkin and Melanie.
All three tumble down into one of the sinkholes. The Flash, still virtually paralyzed by Melanie's terror, is helpless before Yorkin. Getting a firm grip on the Flash, Yorkin begins draining away the Scarlet Speedster's life essence. Fading fast, the Flash sees an image of his deceased wife, Picture News reporter, Iris West Allen. The image of his wife gives Flash the strength to rally, which sours Yorkin's psychic feed. Yorkin breaks contact and attempts to scale the walls of the sinkhole. Unable to find purchase, Yorkin falls back. The ground gives way beneath Yorkin, as the Earth swallows him whole. The Flash manages to get Melanie to safety before the entire sinkhole collapses in on itself.
Melanie had locked onto the Flash's vision of Iris and used her psychic powers to feed the image back to him on a continuous loop, for him to draw strength from. The Flash gets Melody home. With Yorkin dead, the Flash has finally avenged the murder of his wife. Back at police headquarters, the Flash, as Allen receives a phone call from his friend, detective Frank Curtis. Allen is stunned when Curtis tells him he has ironclad evidence that proves, beyond a shadow of a doubt, that Yorkin did not kill West-Allen. The murderer of the Flash's wife is still, very much, at large.
