Synopsis for "The Man Who Broke the Time Barrier!"
Central City is hit with a number of strange crimes where a series of items begins vanishing from people's possessions. Barry Allen becomes involved as the Flash when a beaker he's experimenting with vanishes as well. Tracking down the culprit puts Barry up against Mazdan, a criminal from the future who was supposed to be sent to the 50th Century to serve his sentence on a desolate Earth but was sent to the past by mistake instead.
Able to avoid Mazdan's weapon, Flash captures the crook. However, he manages to break out of prison using his superior scientific knowledge. Catching up with Mazdan again, the Flash tries to capture him again but stops when Mazdan petitions the Flash to allow him to return to his own time. Instead of allowing him to go in his own time capsule, the Flash instead breaks the time barrier by running at super speed, turning Mazdan over to the authorities in the future. Mazdan is sent to the correct era to serve out his punishment. The Flash then returns to his own time and resumes his civilian life once more.
