A killer who is bitter toward the health-care industry murders the CEO of a healthcare system and an oncologist. At the lab Adam finds himself against a highly intelligent tech-savvy suspect as he and Mac race against the clock to identify him. The case turns personal for Mac when the suspect calls and taunts him by mentioning the name of Mac's father, who died nearly 20 years earlier.

A night-shift janitor is found hanged on Ellis Island and the apparent suicide is quickly ruled a homicide. The killer left behind an antique compass as a clue.

A rising star in the underground world of street-dancing competitions is murdered in his hotel room shortly after winning a contest and his girlfriend is beaten. The investigation rules out robbery as a motive since the victim's prize money wasn't taken. The chief suspect is a rival dancer who placed second in the competition.

A software-company executive bleeds to death on the street. Hawkes believes he may be responsible because he attended to the victim just hours before in the park as part of a volunteer medical service and didn't think the man's condition was serious. The investigation takes the CSIs into the underground world of "food sploshing" parties, in which participants use food in sensual ways. Hawkes reveals a surprising secret.

Ray Langston of the Las Vegas crime lab follows a human-trafficking ring that specializes in black-market organ harvesting to New York, where he assists Mac in attempting to free a hostage taken by the criminal group.

Responding to a call for help from 911, the CSI's discover a nearly 100-year-old corpse. After Stella narrowly avoids death by the same trap that killed the victim, the CSI's must then figure out the riddles of the penthouse to locate the 911 caller, and the caller's girlfriend.

The team learns that a former drug addict, who had been clean for two years, has been hit by a car and it seems that a two million dollar life insurance policy was behind his death.

Suspects include his wife, whom he had promised he would retire, his racing rival (Danica Patrick) who had threatened him, a younger racing driver, and his manager.

A man celebrating his 21st birthday is found walking in the street, covered in blood and attacking cars with an axe. The CSIs find four bodies (two of them the man's friends, the others two unknown girls) in the man's hotel room, but soon they prove that the man (who is suffering from LSD-based hallucinations) is innocent. The team must retrace the man's steps through the night so they can find the killer. In the end they find that the girls (who were the ones that dosed the man with LSD) worked for a drug lord and wanted to leave, with the man and his friends meeting them as the girls escaped: the drug lord killed the four victims, which the man witnessed - and Mac ends up saving him when the drug lord tries to kill him.

This is revealed to be a plot by Shane Casey, who is using the murder as a distraction to escape using Danny's stolen badge. In the process, the prison cells are unlocked, resulting in a prison riot.

A man is found at a construction site, completely encased in fresh concrete. The investigation takes a more dramatic turn when the victim is revealed to be dressed like a Roman gladiator and participated in underground fighting competitions broadcast over the Internet.

Mac investigates the shooting of a 14-year-old boy, while he and his younger 12-year-old brother walked home from school. Since the younger brother is the only witness, he points out who did it. However, the suspect can only be charged with stealing the boy's watch, and no evidence points to him committing the shooting. As Flack becomes personally involved in the case, the CSIs learn that the brothers robbed a bank to help their mother pay the rent, and it was another suspect who did the shooting.
