Synopsis:
The Flash is contacted by Colonel K, a secret agent for a intelligence agency. He is tasked with the job of locating a new super weapon known as the Y-Missile in China. The Flash searches the entire country and eventually finds the missile site just as the Y-Missile is being launched. He holds on to the missile which speeds around the world and is set to land in the center of the United States. The Flash disables the missile by destroying the homing beacon which served to guide the missile. With the beacon destroyed, the threat is ended.
