CSI: Miami

When a rabid dog kills a janitor at a renowned tennis academy, it's clear someone engineered the attack to target Coach Larry Hopper, Miami's most popular tennis coach. The team discovers Hopper was involved in a child sexual abuse case ten years prior, but settled out of court. Could the victim now be back for revenge? Calleigh learns that Austin North is a student at the academy and grows suspicious when pro player and academy alumnus, Jack Brody, takes a special interest in him. Forensics prove that Brody orchestrated the attack, and he eventually confesses to sending in the wild dog in an attempt to prevent Hopper from molesting Austin next. It's also discovered that the janitor knew that Hopper was assaulting young boys but chose to look the other way.

When a freelance journalist is poisoned, the CSIs must figure out if her murder was provoked by a story she was doing on Miami Councilman Randall Stafford. After Stafford's DNA is found at her apartment, his attorneys, Darren Vogel and Gabrielle Wade, are able to dismiss the evidence on grounds of tampering. The team begins suspecting the journalist was actually doing a story on Vogel, not Stafford, after discovering that Stafford helped cover up a murder committed by another of Vogel's clients. It turns out that Vogel is blackmailing his clients to facilitate his firm, and he likely had Denise killed after discovering she was on to him through Stafford. Before they can arrest Vogel, Gabrielle admits to being the sole instigator of the firm's criminality, even though Horatio suspects Vogel is blackmailing her into being his scapegoat. And Calleigh reveals to Eric that she is thinking of adopting Austin and Patty North.

CSI Wolfe is a suspect when one of the team's enemies, ASA Josh Avery, is murdered. When the investigation becomes deadly, Samantha Owens ends up having to be rescued. The episode ends with Ryan's discovering that Sam is the one responsible for killing Josh. Also, Calleigh ends up adopting Austin and Patty North.
