Mad Dr. Doom completes his "Walking Dazed" formula and tries it on captives Betty, Veronica and Pop Tate. It works exactly as planned, sapping the wills of his captives and making them his slaves. The next phase in the plan is to introduce the formula into the school lunch at Riverdale High. In addition, the criminals attack P.O.P. Headquarters with more of the formula. Archie, Chuck and Jughead arrive at the hidden POP spybase to give Andy a warning about Mad Dr. Doom when they are surrounded by "Waking Dazed" zombies.
