Mansion

One night two siblings, Samantha and Jonathan, come across a butterfly while exploring a grassy field. Enchanted by the butterfly's haunting beauty, Samantha chases after it. Jonathan follows reluctantly, repeating their grandmother's warnings about ghosts who roam the area and turn people into butterflies. The butterfly leads Samantha into the Mansion, where she becomes trapped.
