Betty, Veronica, Cheryl, and the rest of the River Vixens are heading out of town for the weekend on a cheerleading retreat, a few days of nature and team bonding. But when they arrive at the cheerleading camp, there are two other feuding squads already there. The team from Stonewall Prep claims that the Greendale girls are the reason one of their teammates went missing two years ago. Betty and Veronica volunteer to investigate after creepy things start happening all over camp. And when one of the cheerleaders nearly drowns in the lake, B&V know they have to find out the truth before anyone else gets hurt – or worse.
