Archie's on trial for murder, and the evidence is stacked against him. Betty, Veronica, and Jughead all know that Archie is being framed by Hiram Lodge, but how can they prove it? The gang comes up with a last-ditch plan to prove Archie's innocence: They have to go back to the scene of the crime. They have to go back to Shadow Lake. Threats are around every corner deep in the woods at the Lodge family cabin. Will the teens find the evidence they need to clear Archie's name? And more importantly, will they make it back to Riverdale alive?
