CSI: Crime Scene Investigation is a drama series about a team of forensic investigators trained to solve criminal cases by examining the evidence. The team from the Las Vegas Crime Lab is on the case 24/7, scouring the scene, collecting irrefutable evidence and finding the missing pieces that solve the mystery. The series made "DNA" a household term to millions of fans in over 170 countries who learned the importance of blood, saliva, and skin as evidence and how those elements help solve crimes. The CSIs sift through the murders, suicides, robberies, and violent crimes that threaten the streets of Vegas, on and off the Strip, moving beyond the neon decadence to the seediest and deadliest corners of the infamous city in the desert. The team uses both cutting-edge scientific methods and old-fashioned savvy to solve their crimes, driven to succeed by the pact they have made with the public they serve — "Let the evidence bring justice to the victims and closure to the survivors."
