This East End Kids comedy has the boys heading off to a mountain camp for a summer vacation. While heading to the camp, they hear about a "monster killer" roaming the area and end up meeting Nardo (Bela Lugosi), the creepy owner of an old mansion. When one of the boys is injured in their late night hunt for the killer, they end up taking refuge at Nardo's mansion, where strange goings on and misunderstandings add to the hilarity.
