The Flash helps out on a movie set when Steve Palmer, an actor playing Flash, is in danger.
Reporter Iris West is on assignment in Hollywood. The Flash, also in Hollywood to consult on the filming of a Flash movie, consents to an interview.West is surprised that the Flash isn't actually starring in his own film. During the course of the interview, West hits upon the idea of inviting her boyfriend, police forensics scientist Barry Allen, out to Hollywood. Unbeknownst to West, Allen is also the Flash. As West goes to phone Allen, the Flash bolts out of the restaurant, races across country, and arrives in Allen's apartment in time to answer the call. The Flash, as Allen, consents to spending his vacation, in California, with West.Then, the Flash races back to the restaurant.
The Flash gets back to their booth, before West can return to the table. When West criticizes Allen's chronic tardiness, the Flash enters into a friendly wager with West, guaranteeing that Allen won't be late for his date with West. The Flash returns to the set of the movie, concerned over several attempts on the life of the film's star, Steve Palmer. In the projection room, the Flash watches the latest dailies for the film. In a sequence called "The Doomed Scarecrow", the Flash himself steps in for the filming, The Flash uses his super-speed to stop incendiary bullets from igniting a scarecrow, filled with hidden evidence. The Flash takes Palmer's place in the film, in order to catch the would-be killer.
As all of Palmer's mysterious "accidents" have revolved around equipment failure, suspicion falls first on the prop man, Hank Walters. Rather than bother with special effects and film trickery, the Flash opts to actually use his powers in his portrayal of himself. The Flash is called, along with several extras, to film the "mine scene". While the Flash goes over the script with the extras, an explosion causes a real collapse in the mine. Moving at super-human speed, the Flash quickly digs a tunnel to the surface, before the air runs out underground. Returning to his trailer, the Flash is hit from behind, and wakes up bound in ropes.The would-be killer turns out to be Palmer himself.
Palmer rigged all of his "accidents" in the hopes of getting the Flash to take his place in the film. When the mine collapse failed to kill the Flash, Palmer hid in the Flash's trailer to ambush him. Palmer intends to replace the Flash, cashing in on the Flash's name to make millions through endorsements. Palmer, and his men, are about to gun the Flash down, when West comes knocking at the Flash's trailer door. Their attention drawn to the door, the Flash uses the distraction to vibrate out of the ropes. The Flash attacks Palmer, and his men, quickly taking them all out. At the Brown Derby, West seemingly wins their bet, when Allen fails to appear. The Flash departs. West walks to her booth to discover Allen sitting there, waiting for her. The Flash has won the bet, after all.
To gain entry into the Eta Pi Fraternity, of Blue Valley High School, Wally West and Peter Willard are required to stay, in a reputably haunted house, until Midnight. Nervously talking to get his mind off ghosts, Willard reveals that while he may believe in ghosts, he doesn't believe in Kid Flash. Willard cites a recent incident at the school, where Kid Flash supposedly played every instrument in the school's orchestra at the same time. West assures Willard that Kid Flash did, in fact, perform that particular feat. The sound of chains clanking heralds the arrival of a pair of ghosts, who chase the boys out of the house.
Willard runs screaming into the darkness, but West returns to the house, as Kid Flash. Moving faster than the eye can see, Kid Flash discovers the "ghosts" are really a couple of crooks, using the "haunted" house as a hideout. Covering himself with a sheet, Kid Flash, moving at super-speed, creates the illusion that the house is actually full of ghosts. The two crooks tear off into the night, with Kid Flash pursuing them. Kid Flash herds the two crooks towards the nearest police station. Kid Flash heads off to look for Willard.
In the darkness, Willard has caught his foot between two stones, at the base of a hill. A lightning bolt strikes the top of the hill, starting a landslide of earth and stones. Responding to Willard's cries of distress, Kid Flash races across the face of the hill, deflecting all the stones away from Willard. Once Kid Flash frees Willard's leg, he returns to the house, as West. Willard returns, as well. Once the midnight hour has struck, the two boys have earned their pace in the Eta Pit Fraternity.
