Helena and Detective Reese clash again when they both try to track down a serial killer who destroys metahumans by taking on their powers. Meanwhile, Dinah ditches school when she learns from Helena there is a metahuman-only bar, and Barbara meets Wade's parents who think she is not normal enough for their son.

When Helena's former classmates descend upon New Gotham for their fifth class reunion, two of the alums are brutally murdered. While Helena tries to find the killer, she fears that Reese's investigation will lead him to learn too much about her true identity.
