When a couple is murdered after meeting another couple in a bar, Grissom and his team suspect it is the work of a pair of serial killers. Nick jeopardizes a case when he gives an old friend some information, and it later turns up on the local news.
Continuing from the previous episode, the suspects of the two murders, a husband and wife, are killed in their own house which was being watched by two undercover officers working under Jim Brass. The two officers were missing during the murder because they were called in to a possible shooting which turns out to be a hoax. Sara and Catherine are pulled off the murder case to investigate the death of a college student found bloated in a bathtub.
Grissom investigates a home invasion which results in the death of an old woman living alone in her house. She is found, mummified, in a closet. Her death is probably unintentional. Another home invasion is also reported. Finger prints from the two crime scenes link the two incidents together. Meanwhile, Catherine must find out how a gun ends up in a front lawn of a house in the suburbs.
A heat wave hits Las Vegas. A baby boy is found dead inside a locked car, apparently accidentally forgotten by his father. Another case involves a man found dead in his house, possibly from a heat stroke. Nick and Sara investigates the death a teenage girl found in a lake with a head wound.
There was a car accident. Besides the dead driver, another dead body lays on the side of the road. He is wearing a mascot-type suit of a raccoon. He died from a bullet wound. His furry costume leads the detectives to a convention for people who identify themselves as animals, expressed via their costumes. A second case involves a dead man found in a freezer. Like the first victim, he also died from a bullet wound.
Dr. Robbins receives an embalmed head from Jackpot, Nevada. Working solo, Gil Grissom heads out to this small town to gather evidence that will help crack the case. No one in town seems very enthusiastic about finding the rest of the body and many of them act suspiciously. The sheriff assists Grissom in his search. The body is finally found, buried up to the neck. Back at Las Vegas, Catherine receives a check from Sam Braun, her biological father, in the sum of $250,000. She attempts to return it to him.
During a preliminary trial for the rape and murder of a 19-year-old woman, the crucial evidence, a bloodied knife, is discarded because it was secured from the defendant's car without a warrant. With only 24 hours left before court has to let him walk, the team pools their resources together in an attempt to find other evidence that can place the defendant behind bars.
Julie Waters, a dancer, has been missing for 6 days. A suspect, Howard Delhomme, calls the police and turns himself in. He refuses to talk to anyone but Catherine. Sarah and Nick want to work on this case because they see it as a career-making step. Grissom, to their anger and disappointment, hands the rein over to Catherine. Despite their initial antagonism, they all worked together to find the young girl.
Grissom, Catherine and Nick investigates a car bomb which resulted in the death of three people, one of whom was an air marshal who rented the car. Due to the imprecision of the detonator, the CSIs conclude that the target may not have been the air marshal but the person who had previously rented the car. The man is a mystery himself, as he seems to be leading a double life. In town, Sara and Warrick works on the death of Amelia, the wife of Myles Reuben who is a famous singer. She was found in her hotel's bathtub while her husband is performing downstairs.
A teenage boy is found dead on a construction site. He appears to have suffered multiple blunt force traumas on his whole body. The murder weapon is likely a hammer. A ripped fabric found in his hand leads the investigators to a young girl who knows the deceased. Another case is very puzzling. A woman dies from a bullet wound in the chest while trying to break a fight between her present husband and her ex-husband. None of the men have GSR on their hands and no gunshot was heard.
A nurse is found dead in her house by her friend, who's also a nurse. The victim died in her spacious bathroom, posed with her head facing the door. According to the friend, she was to have dinner with her new boyfriend, Dr. Michael Clark, who works at the same hospital. Processing the crime scene reveals very little evidence because the killer has thoroughly cleaned the place and used bleached to denature any DNA. Dr. Clark, initially a prime suspect, is later found, albeit in pieces, in garbage bins behind the house. The precision of various cuts suggests that a medical personnel is the killer. Meanwhile, this case prompts Grissom to contemplate his workaholic life and whether it is worth the life he may be missing out on.
Nothing is as it seems when the CSIs are called in to investigate an apparent death in a hotel pool by electrocution. It turns out that the body is a dummy. The real crime scene is inside the hotel when an antique Japanese sword is stolen from an exhibition. As this investigation proceeds, the detectives will find that there are more deceptions in play. Another case involves the death of a teenage girl who's into the vampire cult. All the blood in her body has been sucked out.

Two masked men show up at a house and kill the husband and wife execution-style with two bullets at the back of the head. The man's body is then dragged from the fairly secluded driveway towards the street, a fact that greatly puzzles Gil Grissom. The couple lived at a very good and secured community with only two entrances, the main gate to the whole complex, and a personal back gate.
A man who works at a half-way house is found dead in an area filled with drug addicts and prostitutes at night. His belongings were stolen, form car to shoes. Another body is found wearing only his boxers with signs of a clown's make-up.

A very large man is beaten to death by a smaller man with enormous strength. During interrogation, the suspect jumps on Grissom and is subdued by police officers in the room. He ends up dead, not from being beaten, but from cardiac arrest. The findings in his stuffed car, which includes a waitress uniform, leads Grissom to investigate the dead man's motel. The result shocks the team when a skeleton of a woman is found buried in his property.
A teenager dies from inhaling smoke during a fire before firemen could rescue her. The rest of her family, her mother, younger brother, and grandmother are safe. Catherine, Nick and Warrick works on the case which unveils an unexpected and shocking finding. Gil Grissom and Sara investigates the death of a man found in a hotel's bathroom. Autopsy reveals that he had swallowed 6 pieces of game tiles and had suffocated to death. The tiles lead the two detectives to an annual championship of Logos, a word game similar to Scrabble.
The team investigates the death of three police officers in a time when over 20,000 policemen gathered in Las Vegas for a marathon. One of the bodies, a male, is found by Grissom and Catherine during their run in the race a little off the route. Two others, a man and a woman, died from gunshot wounds in the man's hotel room.
Three crimes are explored in this episode. Firstly, an employee of an amusement park is found dead due to head injury, near a roller coaster accident where a car came off the tracks, leaving several passengers dead. Foul play is suspected. It is believed the murder and the roller coaster damage are linked. Also, a 13-year-old girl is found dead outside, again cause of death from a head injury.
The body of a young gambler is left at a neon graveyard. He died from two gunshots to the back of his head. Prior to his death, he won a lot of money from one of Sam Braun's casinos. This makes Grissom remove Catherine from the case.
A raped victim identifies her attacker from a line-up, after correctly giving the investigators his license plate number and physical description. DNAs recovered, however, indicate that the suspect is not guilty, as only 7 out of the 13 alleles matched, which suggest that the rapist is a relative. The suspect's brothers are all tested for their DNAs and none are a positive match. The resolution of this investigation is a shock to everyone due to the rarity of a genetic condition.
