24 Episodes 2006 - 2007
Season 7 begins with a murder at Cirque du Soleil and Catherine (Marg Helgenberger) drugged at a nightclub. She awakes, nude, in a hotel room and starts processing herself. Later, her daughter Lindsey (Kay Panabaker) is kidnapped\, and Catherine realizes they are pawns in a cat-and-mouse game involving her father Sam Braun (Scott Wilson). Meanwhile, Grissom (William Petersen) and Sara (Jorja Fox) investigate the murder of an aging rock star (guest star Danny Bonaduce) who is found dead in his kitchen near an exact replica of the crime scene. He's the first victim of the Miniature Killer, who leaves handcrafted and meticulously detailed replicas of his or her murders. As the season progresses, clues come to light and a replica is delivered to Grissom of a crime not yet committed that targets a member of his staff. But before that occurs, Grissom goes on a four-week teaching sabbatical, and his departure proves difficult for Sara. To help cover the night shift while Grissom is away, Mike Keppler (Liev Schreiber), an experienced CSI from Baltimore who is the latest hire on the day shift, comes aboard. But his not-always-by-the-book methods, including faking a crime scene and deceiving colleagues, cause friction within the lab and lead to violence. And Greg Sanders (Eric Szmanda) accidentally kills a young man with his truck while attempting to rescue another man who is being beaten by a gang headed by a thug dubbed Pig (guest star Kevin Federline). The death leads to an inquest and threats from the victim's family. Other compelling happenings include: Five corpses in the morgue describe their bloody deaths to each other; identical twin sisters who didn't know of each other's existence are murdered on the same night; a sadistic client of Lady Heather (Melinda Clarke) tries to murder her; and the remains of a '70s Vegas crime boss are fished out of Lake Mead, and the investigation centers on several suspects, all played by the Who's Roger Daltrey.
