Ash and his friends find themselves in a mansion called the Scary House to shelter from the rain. Its owner Lon offers them some food. A Gastly, Haunter and Gengar scare Ash and his friends as a playful way of showing hospitality. Ash, Pikachu, Serena and Bonnie fall down some trapdoors into the basement. After rescuing them, Clemont finds a 200-year-old journal which talks about the secret room the trapdoors lead to which was created for Lon to hide in when he was a boy. Ash and the others are shocked to discover a 200-year-old photograph of Lon and that Lon is no longer alive. Afterwards, everyone wakes up in the forest, with Ash, Serena and Clemont unsure if they were dreaming. (Source: Wikipedia)
