Detectives Goren and Eames are investigating the death of a condominium association president who was murdered with an electrical saw.
The investigation reveals the many secrets hidden behind the walls of the sophisticated luxury tower, as Goren and Eames focus their attention on the building's construction defects, as either a by-product of inadvertent onsite errors or slapdash, product failures, hurried maintenance.
The detectives find they need one more missing link to make their case, and subsequently examine the suspicious behavior between other owners. Finally, the interviews of a young nanny helps them put the pieces together.
