The second season begins with an expert climber scaling the Empire State Building and witnessing a murder on the 34th floor before falling to his death. Mac and Hawkes, who recently transferred to the field, work the case. The murder victim is the head of a prestigious law firm located in the building. Across town, Stella investigates the death of a man found wearing a diamond-studded bra worth millions, and Aiden tracks a rapist who attacked the same woman twice.
