Dexter Myles, the curator of the Flash Museum, leads a police officer to a grim tableau. Within the museum, the lifelike wax figure of the Flash has been laid prone, at the feet of wax figure replicas of Captain Cold, Captain Boomerang, Heat Wave, and the Pied Piper. A flash bulb alerts Myles, and the officer, to the presence of a reporter, who flees without identifying himself. Myles calls the home of police forensics scientist, Barry Allen. Allen's houseguest, Stacy Conwell, takes the call, while Allen listens in on another line. Conwell is surprised that Myles doesn't remember her. Allen, as the Flash, races over to the Flash Museum, arriving in time to thwart a robbery.
The Flash confesses to Myles that he set up the tableau. Furthermore, it was the Flash who posed as the reporter, then sent the photograph to the newspapers. This elaborate ruse has been set up to flush out an assassin called "Saber-Tooth". Through his underworld contacts, the Flash has become aware of Saber-Tooth's presence in Central City. Knowing that Saber-Tooth is gunning for him, the Flash made it seem as if one of his Rogues' Gallery also had a scheme in place to take down the Flash, in the hopes that it would force Saber-Tooth's hand. Myles reveals himself to be Saber-Tooth, at which point, the Flash really is struck down by the weapons of the wax replica Rogues.
After photographing the Flash's body, Saber-Tooth heads out to the woods, to dispose of the real Myles. Before he can murder Myles, a tree suddenly falls down upon him. Before it can hit, the tree is shredded into wooden strips, at super-human speed, which are then used to cage Saber-Tooth. The Flash reveals that he avoided Saber-Tooth's trap by vibrating his molecules into intangibility. The Flash knew all along that "Myles" was Saber-Tooth, because the real Myles never would have forgotten meeting the beautiful Conwell.
On the planet, Que, an alien Sposm tank, and a terrestrial World War II era Sherman tank have been forced into combat with one another. Alien gamblers have laid out a wager on the outcome. Between the two tanks lies the unconscious body of the Green Lantern. Revived by his Power Ring, the Green Lantern deflects an attack from the human tank crew. Encasing the Sherman tank in a force field, the Green Lantern turns, just in time, to deflect an attack from the Sposm tank. The Sposm shell, however, was no ordinary explosive, but, in fact a blob of plasm.
Enough of the plasm strikes the Green Lantern to stagger him. Using their Omnitron, the aliens dissipate the Green Lantern's force field, surrounding the Sherman tank. The two tanks begin firing upon one another. Stray fire strikes the Omnitron, bathing the two aliens in it's aggression enhancing radiation. The aliens begin fighting, one viciously beating down the other. The alien victor, exhilarated by his triumph, charges the dueling tanks. Before the Green Lantern can end the combat, the alien is torn to pieces by the tanks' crossfire. The Green Lantern returns the two tanks to their proper places and times, leaving the surviving alien to grieve for his friend.
