A new trailer for "Riverdale" has been released by The CW. The video begins with Archie (KJ Apa) making out with young music teacher Ms. Grundy (Sarah Habel) in a remote area. They're later surprised by a loud noise from another direction.

Another scene shows two guys discovering dead body of Jason Blossom floating in the water. We then see Archie's buddy Jughead Jones (Cole Sprouse) getting mad and saying, "A kid is dead, Archie! And she's telling you not to say anything."

Based on the trailer, it appears that Archie and Ms. Grundy witnessed something that day which can explain the mysterious death of Jason. But they probably can't share the information to keep their forbidden relationship a secret.

"Riverdale" also stars Lili Reinhart as Betty, Camila Mendes as Veronica, Ashleigh Murray as Josie McCoy, Luke Perry as Fred Andrews, Madelaine Petsch as Cheryl Blossom, Ross Butler as Reggie Mantle, Casey Cott as Kevin Keller, Madchen Amick as Alice Cooper, Marisol Nichols as Hermione Lodge, Shannon Purser as Ethel Muggs, and Robin Givens as Mayor Sierra McCoy.

The teen drama is penned and executive produced by Roberto Aguirre-Sacasa ("Supergirl", "Glee") along with exec producers Greg Berlanti ("Dawson's Creek"), Sarah Schechter and Jon Goldwater. The series is directed by Lee Toland Krieger.

"Riverdale" will premiere on Thursday, January 26 at 9 P.M. ET on The CW.
