Chain Reaction is the seventh episode in season six of CSI: Miami.
A very gorgeous model dies by electrocution on a runway during a fashion show, and the investigation reveals the death wasn't an accident but murder. The probe also turns up evidence that the victim is connected to the man who kidnapped Horatio's son, which may mean that Kyle is in greater danger than Horatio feared.
An extremely beautiful model named Alisha Reilly is electrocuted to death at a fashion show, and the CSIs quickly determine her death was no accident. Their top suspect is the lighting technician, Terrence Kerr, until they discover red hair from Juliana Ravez, one of the other models, beneath the stage. Juliana claims she hooked up with Terrence in order to ensure she'd get good lighting during the show. The CSIs are surprised to learn that Alisha was married to Joe LeBrock, an inmate with a grudge against Horatio. When Horatio questions Joe, he makes a veiled threat against Horatio's son, Kyle, and the man Horatio asked to look out for him, Oscar. Horatio warns them both. The CSIs learn that Joe had a visit from his son, Scott, but when they learn the FBI is investigating Scott, Natalia is called upon to use her FBI connections to find out why Scott is under investigation. She isn't able to discover why, but Natalia is able to get surveillance tapes out of her contact Agent Farallon.
Calleigh and Delko go over Alisha's clothes and are surprised to discover heroin embedded in the metallic fabric. They corner the designer, Gavin Hauer, and find his lab. He admits to them that he has been smuggling drugs for Joe LeBrock. Horatio goes to the prison to confront LeBrock only to see Oscar killed before his eyes by a landmine. Delko finds a SIM card from a cell phone among the debris, and when the inmates' cells are searched, a phone is found in Kyle's bed. Kyle claims he has no idea how the phone got there. Delko goes over the entire wardrobe from the fashion show and finds a platinum string missing from Juliana Ravez's dress and concludes that it was the platinum string used as a conductor to kill Alisha Reilly. Calleigh and Delko confront the model, who admits she killed Alisha when she learned Alisha was going to blow the whistle on the smuggling operation. She did it without Joe's knowledge; she wanted him for herself.
Horatio learns that Kyle lied to him about the phone when he finds calls on it made to Kyle's mother in Pensacola. Kyle admits Joe gave him the phone as a peace offering. Horatio is able to find the inmate who LeBrock got to sneak into Kyle's cell and detonate the bomb with the phone, but he won't testify against LeBrock. Rebecca Nevins is determined to go ahead with charging Kyle with the murder, with LeBrock as a witness against him. Ryan and Natalia find the key: video footage from the FBI revealing Scott LeBrock trying to entice a little boy into his car. He's a pedophile, and when Horatio confronts Joe with the evidence, he reminds him that pedophiles—and their relatives—are at the bottom of the food chain in jail. Joe folds, refusing to identify Kyle in court as the one he gave the cell phone to.
