When someone's murdered, seemingly via her discovery, physicist Madison Martin knows it's her responsibility to bring the killer to justice. Madison resumes her quantum cop role to help the local cops and the F. B. I. investigate everything from quantum panty raids to impossible heists and increasingly bizarre murders. As the q-crimes increase, she worries that reality itself is a goner. When Madison's nearly obliterated in a quantum duel she realizes she can't handle it by herself. But this leads to another problem: does her overworked task force include the very criminal she's trying to catch? And if so, can she take him down before it's too late?
