When a tainted batch of fizzle rocks makes its way through Riverdale, Jughead (Cole Sprouse) and FP (Skeet Ulrich) set out to find who’s responsible. After asking Veronica (Camila Mendes) to help get him into an upcoming boxing tournament, Archie (KJ Apa) quickly learns he may be in over his head. Elsewhere, Betty (Lili Reinhart) makes one last attempt to rescue Alice (Madchen Amick) from The Farm’s grip, and Toni (Vanessa Morgan) becomes unsettled by a sudden change in Cheryl’s (Madelaine Petsch) behavior.
