With CSI: Vegas, the most watched drama series of the 21st century, CSI, opens a brand new chapter in Las Vegas, the city where it all began. Facing an existential threat that could bring down the Crime Lab, a brilliant team of forensic investigators must welcome back old friends and deploy new techniques to preserve and serve justice in Sin City.

CSI: Cyber is a drama inspired by the advanced technological work of real-life Cyber Psychologist Mary Aiken. Special Agent Avery Ryan heads the Cyber Crime Division of the FBI, a unit at the forefront of solving illegal activities that start in the mind, live online and play out in the real world. While other FBI agents search for criminals in dark homes and alleys, Ryan and her team search the "dark net," a place deep in the bowels of the Web where criminals are anonymous, money is untraceable and where everything is for sale with just a keystroke.

The third edition of the CSI franchise sets up shop in the Big Apple, where taciturn former Marine, Detective Mac Taylor leads a crime-solving team of police officers and forensics specialists. In the city that never sleeps, CSI: NY never rests, and while people may lie, the evidence rarely does.

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.
