“CSI”: The Basics
The CBS network gave the order a little over a year ago for “CSI: Vegas,” a revival of the original “CSI” series that launched the franchise. This groundbreaking series is one of the biggest shows in TV history, ranking in the top 10 most-watched ones and spanning 337 episodes over 15 seasons. The series finale in 2015 included a two-part wrap-up movie, although the spinoffs continued. This fall, the original series is unwrapped for a whole new generation of crime scene enthusiasts.
“CSI” stands for crime scene investigation. It’s a procedural forensics crime drama that follows a team of investigators working for the Las Vegas Police Department who use physical evidence to solve murders. As the second-largest crime lab in the country, the CSI team deftly solves crimes that other investigators have given up on with careful scientific analysis and occasional logical leaps.
Set in Las Vegas against a gritty background full of visitors and vagrants, the hopeful and the naive, the team’s obsessive dedication helps them find the truth among the lies through the evidence.

“CSI”: A Breakdown of Each Season
A lot happened in those first 15 seasons, which comprise a total of 337 episodes that are hard to remember to the tiniest detail. Apart from the numerous eventful episodes, it may have been a few years since you watched the finale in 2015. So, we’ve provided a recap of each season to get you back up to speed (or to fill you in if you’re new to the “CSI” world).
Leading off with the shooting and ultimate death of CSI Holly Gribbs, the first season follows the team at the Las Vegas Crime Lab as they work to solve strange and often brutal cases. Supervisor Gil Grissom and his second-in-command Catherine Willows lead the team to investigate suicides, burials, a severed leg, a skeleton, and other murders. On the personal front, CSI Brown faces a gambling addiction, CSI Sidle adjusts to her new Las Vegas life, and night shift supervisor Brass gets acquainted with the homicide squad.
Season two starts with a trip to Miami to investigate the murder of a police chief. Throughout the season, the Las Vegas CSI team also investigates the murder of the son of a Las Vegas mogul, a university student’s disappearance, a decomposed body in a bag, a scuba diver in the desert, a fetish murder, a spa murder, suicide by train, and more. Warrick is given the opportunity to head the crime lab, Grissom and Willows face a serial killer in court, and Nick Stokes becomes the target of a stalker.
At the start of season three, Grissom suffers from hearing loss, while Willows might lose her daughter. The team investigates the death of a poker player, the evisceration of a cheerleader, a jewelry heist, a body covered in fire ants, a drive-by shooting, and various other murders. The team also faces their past while testifying in court, Sara Sidle struggles with psychological trauma from an explosion, and a victim wakes up on the autopsy table.
Stokes leaks information to a news reporter, and Willows investigates a body in a bathtub at the start of season four. Investigations this season include a disappearing gun, the death of a baby during a heatwave, a man dressed as a raccoon versus a big rig, a car bombing, and a roller-coaster derailment. In addition, the team is tasked with re-investigating a rape and murder. Grissom travels to Jackpot, Nevada, and the team participates in a CSI relay and other investigative teams from across the country.
The Crime Lab undergoes some personnel changes in season five, sending Greg Sanders from the lab into the field. This season’s investigations include the discovery of an “alien” corpse just outside of Area 51, a body washed up after a storm, the kidnapping of a teen, a death at fumigation, a swingers party, the return of the Blue Paint Killer, and more.
When new evidence appears while Grissom is on the witness stand, sheriff Conrad Ecklie decides to separate Grissom and Willows’ team. Willows, Stokes, and Warrick Brown investigate a case of brain death, a body in a car, a severed head containing a snake, the death of a bear, and sports betting murder. The team is ultimately reunited when Ecklie and Grissom set aside their differences after one of their own is kidnapped.
Jim Brass gets caught in a shootout that kills an officer and enrages a Latino community, and later on, he becomes critically injured in a hostage standoff in season six. Grissom and Willows join forces to investigate the death of a movie star, a corpse at a suburban home, a mass cult suicide, and an apparent suicide. Stokes battles with PTSD, tracks down a missing kid, and hunts the head of a civil war reenactor.
Grissom and Sidle develop an intimate relationship in season seven, and a new CSI, Michael Keppler, joins the team. Investigations include a chainsaw massacre, a death at a church, a kidnapping, a series of killings accompanied by miniature figurines, the death of identical twins, and the return of a mob boss. Willows loses her father, Sanders is assaulted, and the team finds a murder suspect trapped in concrete. The season ends on a cliffhanger with Sidle being kidnapped.
After the team finds and rescues Sidle, she later ends up leaving Las Vegas. The team investigates the death of a go-kart racer, a demonic possession, the death of an intersex person, and the murder of a slasher film actress. FBI agents from New York investigate a kidnapping, Willows struggles with the disturbing death of a 3-year-old, and the death of a TV star sends Brass and Grissom to Hollywood.
Warrick Brown is shot and killed outside a diner at the start of season nine, and later, Grissom leaves the team while new CSI Riley Adams joins. The team investigates the death of a woman, a Halloween robbery, an S&M-related murder, an arson-homicide, the murder of an FBI agent, a toothpaste-related death, and a Mexican wrestling-related death. In addition, Stokes investigates the happenings of a seedy motel over the course of a year, David Hodges and Wendy Simms attend a sci-fi convention, and Grissom attends the trial of the Miniature Killer.
Season 10 sees Willows’ leadership skills brought into question and the brief return of Sara Sidle. Investigations include the death of a porn producer, a botched robbery, a cop killed by another cop, the murder of a football coach, a revenge plot, a bowling tournament death, and human trafficking.

After a demotion, Willows and Stokes now work under D.B. Russell. This season, the team is joined by CSIs Morgan Brody and Julie Finlay, and Willows and Stokes ultimately leave. Investigations include the murder of a family, drowning in chocolate, a death at a mob museum, a cold-case killing, the zippering of a body, a sadistic slaying, the theft of a house, a blackout, a murder at an Alice-in-Wonderland wedding, and a race truck explosion. In addition, Russell faces family problems, Brody’s helicopter gets hijacked, Dr. Albert Robbins’ wife is investigated, Ecklie is gunned down, and the Crime Lab is placed under the supervision of an outside agency.
Sidle convinces Stokes to return this season. Investigations include a shootout at a diner, the murder of a runaway sex slave, a body in a piano, the death of a police dog handler, the discovery of a mass grave, a plane crash, a news anchor killed on live TV, the murder of a tennis star, the murder of a singer, a cheating scandal at a poker tournament, a body near a forest reserve, the murder of a ghost hunter, and a body in a mud bath. On the more personal side of the characters, a body is found on Warrick Brown’s grave, Ellie Brass’s past is revealed, Sidle becomes a homicide suspect, and the life of an investigator is on the line during an investigation into a series of Dante’s Inferno killings.
Picking up where season 13 left off, D.B. Russell and Julie Finlay hunt for a kidnapped Morgan Brody.

As the team hunts down the Gig Harbor Killer, they also investigate a fatal shooting at a marijuana store, a chemistry experiment gone wrong, a death at a rehab, a murder in an alley, a murder at a jail, a victim who died twice, and a victim covered in shards of glass. Meanwhile, Brody, Sidle, and Finlay end up in the middle of a shootout at a forensics conference, Russell explores the psychology of killers, and the team reopens an old investigation.
The finale consists of a two-part movie titled “Immortality” in which a casino explosion brings Catherine Willows and Gil Grissom back to Las Vegas to investigate. Many other past and current stars make an appearance as the team attempts to solve the case.
