These 'Riverdale's Season 5 Premiere Photos Show Prom Looks & A 'Katy Keene' Star

It is finally time for Riverdale High's biggest night. When Riverdale returns for Season 5 on Jan. 20, the teen drama will kick off with its highly anticipated prom episode, and new photos from the premiere show off everyone's killer looks... as well as an unexpected guest. Get pumped for what's sure to be a memorable and messy prom night with these Riverdale Season 5 premiere photos.

Originally, Riverdale's prom episode was meant to air at the end of Season 4, but because the final three episodes of that season couldn't be made at the time due to the coronavirus pandemic, Season 5 will now kick off with what was supposed to take place during the final episodes of Season 4: prom, uncovering the truth about the videotapes, and high school graduation. After Episode 3's graduation, the season will enter a much more mysterious phase, which has kept fans speculating for months.

The bulk of Season 5 will take place after a seven-year time jump ages Archie, Betty, Veronica, Jughead, and the rest of the gang up to their mid-20s. Fans have only seen short clips of what everyone will look like after this time jump, and they seem to confirm everyone will be back at Riverdale High as teachers rather than students.

But before that fast-forward, the students are going to say goodbye to high school in style with some stunning prom looks. New photos from the Season 5 premiere show Archie, Veronica, Betty, Jughead, and Toni getting ready and posing for pictures on their big night.

The episode's official synopsis reveals Archie and KO are fighting over admission to the Naval Academy. It also teases that Betty and Jughead are going to uncover more clues about the videotapes mastermind, and that there may be some trouble brewing for Cheryl and Toni:

Betty and Jughead's investigation into the auteur leads them to the discovery of a secret underground for red-band screenings. Elsewhere, in order to impress the visiting Naval Academy Commandant, Archie agrees to participate in a boxing exhibition against another candidate — KO Kelly. Meanwhile, as Cheryl prepares for prom, she stumbles upon a major secret that Toni's been keeping from her.

The Season 5 premiere of Riverdale will air Wednesday, Jan. 20, at 8 p.m. ET on The CW.
