Harley Quinn...and that OTHER Harley Quinn* well* they got a problem. Somehow* someway* one of these Harley Quinns rode off in baby Kal-El's lil' rocket ship before he could leave Krypton way back whenever that was. She also* just MAYBE* distracted Barry Allen before that lightning bolt could hit* and don't get me started about all the other heroes. So now the whoooole DC Universe is all screwed up and these two HQs gotta figure out a way to put baby Supes back in the rocket before Krypton goes boom* Barry back in front of that lightning bolt* and stop that other Harley before...well* you get the picture. It's going to be bananas.
