Synopsis for Superman and the Flash: "Chase to the End of Time!"

Superman and the Flash are both returning to their home cities following missions out of town. As they both pass through the small town of Rosemont, they spot a strange vibrational ray striking the town from space and both attempt to stop it. When the Man of Steel tracks it to a strange spaceship, he attempts to approach it but it explodes. Elsewhere in the town Flash sees that the strange vibrational ray is causing the townspeople to start to shift into another dimension. Spotting each other, the two heroes work together to prevent this from happening. While the Flash races around the city to maintain its vibrational alinement, Superman ushers the people out of the town and then uses his indestructible cape to prevent the beam from striking the town. He then follows the beam to its source, a massive spaceship locked in combat with another shuttle. Superman scans the ship with his x-ray vision and is shocked to find that it is organic in nature.
