MAC AND DR. HAWKES INVESTIGATE THE DEATH OF AN EXPERT SKYSCRAPER CLIMBER, ON THE SECOND SEASON PREMIERE OF "CSI: NY," WEDNESDAY, SEPT. 21

"Summer in the City" -- Mac and Dr. Hawkes investigate why an expert skyscraper climber plunged to his death while scaling the Empire State Building and the key to the case is the CSI's smallest witness ever -- a mosquito, on the second season premiere of CSI: NY, Wednesday, Sept. 21 (10:00-11:00 PM, ET/PT) on the CBS Television Network. David Von Ancken directed the episode written by Pam Veasey, who is also one of the series' executive producers.

The CSI's offices have relocated to a Manhattan high rise which includes new labs, a staff break room and new office equipment with state-of-the-art technology. Also, after expressing his interest in moving out of the coroner's office, Dr. Hawkes joins the team in the field and his first case has him working with Mac on the death of a skyscraper climber. Although hundreds of witnesses were on hand to see the climber fall, the team suspects foul play and believes someone may have caused his death. Meanwhile, Stella and Danny investigate the murder of a New York fashion designer killed while wearing an eight million dollar diamond bra from his own collection.

CSI: NY, a crime drama inspired by the Number One drama series, "CSI: Crime Scene Investigation," is about forensic investigators who use high-tech science to follow the evidence and solve crimes in the Big Apple. Det. Mac Taylor (Gary Sinise), a dedicated and driven crime-scene investigator who believes that everything is connected and everyone has a story, is a decorated Marine who served in Desert Storm and dabbled in war photography. The job is his life; he focuses on cases until they are solved. He and his partner, Stella Bonasera (Melina Kanakaredes), a well-traveled, well-educated detective, an orphan who flourished in spite of the system, share a passion for the job. Stella is a jack-of-all-trades and has an unmatched desire to find answers for the victims of violent crimes, due in part to questions about her past. They lead a team of experts through the gritty and kinetic city that never sleeps.

The team includes Danny Messer (Carmine Giovinazzo), an investigator with an unflappable spirit and a troubled family history, which he uses on the job as he blends his own set of hybrid ethics. Messer was personally selected to join the team by Mac, and he attempts daily to live up to that honor and responsibility. Sheldon Hawkes (Hill Harper) is the crime lab's former coroner, a brilliant Ph.D. who recently made the transition to the field team. Joining them is Don Flack (Eddie Cahill), an edgy, hardcore homicide detective with a quick wit, impressive forensic insight and a long family history in law enforcement. Rounding out the team is Aiden Burn (Vanessa Ferlito), a smart and sexy investigator whose chameleon-like behavior allows her to adapt to any situation. The New York CSIs may have a different process from those in Las Vegas or Miami, but they are guided by the same steadfast determination. These skilled investigators follow the evidence as they piece together clues and eliminate doubt, to ultimately crack their cases.

CSI: NY is produced by CBS Productions and Alliance Atlantis Communications, in association with Jerry Bruckheimer Television. Jerry Bruckheimer, Anthony E. Zuiker, Jonathan Littman, Carol Mendelsohn, Ann Donahue, Danny Cannon, Andrew Lipsitz and Pam Veasey are the executive producers.
