Strange things have been happening in Ivy Town since Ray Palmer disappeared. In fact, it appears that the the whole town's been experimented on for decades. Enter Ryan Choi - the young hotshot professor who's filling the empty slot on Ivy University's teaching staff... and who inadvertently ends up filling the old Atom's super-heroic shoes!
