When a series of suspicious deaths occur in structures designed by the reclusive architect Elliot Chamberlain, Reeves discovers a pattern others have missed. The buildings themselves are not just shelters, but active participants in a twisted game of architectural justice. Chen, Chamberlain's former protégé, joins Reeves in a desperate race to expose the truth and stop the architect's deadly legacy. But as they delve deeper into Chamberlain's intricate designs, they uncover a conspiracy that reaches far beyond isolated murders. The buildings are not just killing; they are learning, adapting, and evolving. And as the final act of Chamberlain's architectural symphony approaches, Reeves and Chen must confront a terrifying reality: the buildings are not the only ones capable of judgment.
