This was another good movie I watched over the weekend......ending left me shocked and fumbling around looking for that alterante ending!

Description: Jenny (Kelly Reilly) and Steve (Michael Fassbender) are in love and about to get engaged during a calm lake getaway -- but they'll first have to survive a pillaging and murderous gang of kids, led by the psychotic Brett (Jack O'Connell), who suddenly arrives on their front lawn. When Steve tries to quell the violence, matters turn from scary to gruesomely deadly. James Gandhi, Bronson Webb, Thomas Gill and Thomas Turgoose co-star.
