Simon Says (2006)

Synopsis
Danger comes in pairs in this gruesome horror story. Kate (Margo Harshman), Zack (Greg Cipes), Ashley (Kelly Vitz), Riff (Artie Baxter) and Vicky (Carrie Finklea) are five college students who are heading out together for a spring break camping trip. Hoping to add some excitement to the proceedings, they set up camp at the Heathers, a remote wooded location where a notorious murder took place years before. Legend has it a young boy killed his parents and beat his twin brother into a state of severe brain damage in the Heathers, but the students, attracted to the spooky ambience, don't imagine any real danger still lurks in the forest. En route, the kids stop for supplies at a ramshackle general store, where they meet Stanley (Crispin Glover), an eccentric shopkeeper with a mentally feeble brother, Simon (also played by Glover). What they kids don't realize until it's too late is that Stanley is the murderous youngster of legend, and with the help of Simon, he's still in the business of murdering strangers when the opportunity presents itself. Simon Says also stars Bruce Glover (Crispin's father), Lori Lynn Lively and Erica Hubbard. ~ Mark Deming, All Movie Guide
