"Town Of The Timeless Killers"
The Super-Sons stumble into a ghost town where they are ambushed by old west outlaws. It would appear that the town is surrounded by a field that lets anyone in, but no one out. Strangely enough Clark jr.s powers don't work, making it all the easier for the outlaws to add their names to the list of the non-living in this town. (Note: this story taked place outside of Earth 1 and 2 continuity)
