CSI MARATHON: 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. Catherine Willows, a hard-working single parent with a checkered past and a teenage daughter she's raising on her own, heads the team of investigators at the Crime Lab in Las Vegas, following previous leader Gil Grissom's departure. The team's other members include Dr. Raymond Langston, a former pathologist who joins the Las Vegas Crime Lab after consulting on a serial killer case; Nick Stokes, a true-blue stand-up guy who empathizes with victims via his own experiences; and Greg Sanders, the off-beat 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 his assistant, David Phillips; and David Hodges and Wendy Simms, lab technicians with specialties in trace and foreign-substance analysis. .
