Maristrazza is known as an artist and master in the field of architecture, and his architecture is regarded as a model by his peers. Somewhere, a masterpiece of Maristrazza sprang up, but a terrible murder took place here. Many innocent people were built into walls and suffocated by pouring cement, and the building has been abandoned ever since. Fifteen years later, Samantha (Mischa Barton), a beautiful young female demolition engineer, graduates from school and gets the task of demolishing the building from her father. Samantha comes alone and meets the caretaker Mary Souter (Shannon Jardine) and her son Jimmy (Cameron Bright). From the mother and son's mouth, Samantha learned about some taboos in the building, and under the guidance of Jimmy, she gradually found the dark side of the place.
