CSI: CRIME SCENE INVESTIGATION is a fast-paced drama about a team of forensic investigators trained to solve crimes by examining the evidence. They are on the case 24/7, scouring the scene, collecting the irrefutable evidence and finding the missing pieces that will solve the mystery. Gil Grissom, shift supervisor, heads the team of investigators at the Crime Lab in Las Vegas. The team includes Catherine Willows, a hard-working single parent with a checkered past and a teenage daughter she's raising on her own; Warrick Brown, a top analyst with insider knowledge of the gambling world; Nick Stokes, a true-blue stand-up guy who empathizes with victims via his own experiences; Sara Sidle, a dedicated and inquisitive investigator who has more than a professional interest in Grissom; and Greg Sanders, the wacky tech analyst turned field investigator. The CSI team members also work closely with Capt. Jim Brass, the former chief, now assigned to Homicide, Dr. Albert Robbins, the ever-professional medical examiner and David Hodges, a lab technician with a specialty in trace and foreign-substance analysis.

Inspired by the top-rated series "CSI: Crime Scene Investigation," CSI: MIAMI is a drama that follows a South Florida team of forensic investigators who use both cutting-edge scientific methods and old-fashioned police work to solve crimes. Horatio Caine, a former homicide detective, heads a group of investigators who work crimes amid the steamy tropical surroundings and cultural crossroads of Miami. His team includes Calleigh Duquesne, a bilingual Southern beauty with a specialty in ballistics; Eric Delko, an underwater recovery expert who knows all the twists and turns of the Florida waterways, and Ryan Wolfe, a former patrol officer who specializes in blood and trace evidence. Rounding out the team is Alexx Woods, the no-nonsense know-it-all coroner, and Natalia Boa Vista, the enigmatic DNA specialist. Helping Horatio with cases is Det. Frank Tripp, a tough yet thorough police officer. Together, these investigators collect and analyze the evidence to solve the crimes and to avenge those who cannot speak for themselves -- the victims.

CSI: NY, a crime drama inspired by the 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, 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, 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, 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 is the crime lab's former coroner, a brilliant Ph.D. who transitioned to the field team. Joining them is Don Flack, 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 Lindsay Monroe, a young, athletic CSI with a Midwestern work ethic who is willing to roll up her sleeves to tackle any job and rarely hints at the dark and devastating secret that originally motivated her to dedicate her life to being an investigator. 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.
