As a new school year begins, the town of Riverdale is reeling from the recent, tragic death of high school golden boy Jason Blossom — and nothing feels the same. Archie Andrews is still the all-American teen, but the summer’s events made him realize that he wants to pursue a career in music and not follow in his dad’s footsteps despite the sudden end of his forbidden relationship with Riverdale’s young music teacher, Ms. Grundy. Now Archie has no one to mentor him, certainly not singer Josie McCoy, who is only focused on her band, the soon-to-be-world-famous Pussycats. It’s all weighing heavily on Archie’s mind — as is his fractured friendship with budding writer and fellow classmate Jughead Jones.
Meanwhile, girl-next-door Betty Cooper is anxious to see her crush Archie after being away all summer, but she’s not quite ready to reveal her true feelings to him. And Betty’s nerves, which are hardly soothed by her overbearing mother Alice, aren’t the only thing holding her back. When a new student, Veronica Lodge, arrives in town from New York with her mother Hermione, there’s an undeniable spark between Veronica and Archie, even though Veronica doesn’t want to risk her new friendship with Betty by making a play for Archie. And then there’s Cheryl Blossom, Riverdale’s Queen Bee, who is happy to stir up trouble among Archie, Betty and Veronica, but Cheryl is keeping secrets of her own. What exactly, is she hiding about the mysterious death of her twin brother Jason? Riverdale may look like a quiet town, but there are dangers in the shadows.
