Jep and Jess are going on their annual, adults-only camping trip with their friends while Uncle Si babysits the kids. Jess and her friends decide to rent a fancy camper so they can “glamp” in style, but Jep and his friends want to rough it in a tent. When cold weather swoops in, Jep and his friends begin to question their decision to “rough it.” Back at home, the kids are unfazed as they watch a scary movie. Si laments how today's kids are desensitized and takes the kids to a haunted barn, set to prove he can scare them the old fashioned way.
