Cover: a safe falls and hits Superman on the head with no ill effects. Was it an accident or on purpose? 

Superman: Clark is assigned to write up a story about long-distance truckers, so he gets a ride with a cross-country consignment driven by "Gears" Corrigan. Also on board is a new driver, Walt Shade, who is learning the trade from Corrigan. All goes well for the first few hours, but then the truck stops because of what looks like a body lying on the road. The 'body' turns out to be a decoy to force the truck to stop, and a gang of hijackers spring out from the side of the road. Clark manages to slip away to change into Superman, who disarms the hijackers, but before he can capture them, a stray bullet dislodges the truck's brakes and Superman has to prevent the truck from rolling down the hillside, allowing the hijackers to escape. 
 
However, as the hijackers are driving away, Shade picks up a gun they dropped but seems unable to take a shot at them. Corrigan accuses Shade of cowardice, but later, as Shade is asleep in the back of the truck, Corrigan confides to Clark that he thinks Shade might be in league with the hijackers. 
 
When the truck makes its delivery in the next town, Corrigan and Shade are issued with guns to protect themselves from any further hijackers. Suddenly, Clark remembers that he has seen Shade before - as a bank guard some years ago. At the time, the bank was robbed and as the robbers were getting away, Shade also refused to shoot at them. Since there is half an hour before the truck is due to set off again, Clark decides to investigate as Superman. 
 
His first stop is back in Metropolis where he visits gangster Mike Cooley, whose gang carried out the bank robbery where Shade refused to stop them. Despite threats of violence, Cooley denies that Shade had any connection with the gang, and he himself never understood why he let them escape. Next, Superman visits FBI headquarters where he has Shade's fingerprints identified, and discovers that Shade's real name is Walt Brodie, and he is an ex-policeman from Smalltown. On to Smalltown, where the sheriff tells Superman that Brodie left the police after killing an escaping burglar by mistake several years before.  
 
Heading back to the truck stop, Superman discovers that the truck has left without him. On the road, the truck has run into a blizzard, and is again attacked by hijackers. This time, however, Corrigan is felled by one of the gang, and Brodie regains his confidence enough to disable the hijackers. Superman shows up at this point and captures the rest of the gang. Corrigan apologizes for thinking Brodie a coward when he hears his story.
