Ep 8. Nailed

In the CSI Miami season 4 episode 8, titled Nailed, the team investigates a murder at a construction site. The episode opens with the discovery of a construction worker's body who had been shot in the neck with a nail gun. The team arrives at the scene, and Horatio Caine takes charge of the investigation.

The victim, Tom, was a former drug addict who had turned his life around and was working hard to provide for his son. The team suspects that the motive for the murder could be related to Tom's past drug use. They question Tom's colleagues and discover that he had been having problems with a co-worker, who had stolen some of his tools and was causing trouble on the job site.

As the investigation progresses, the team discovers that the suspect had a history of violence and was previously involved in a nail gun accident that resulted in the death of another worker. The team tracks down the suspect and brings him in for questioning, but he denies any involvement in the murder.

The team then turns their attention to the nail gun used in the murder, and they discover that it had been rigged to go off when the trigger was pulled. They trace the modifications back to the suspect, who had been trying to get revenge on Tom for reporting him for stealing his tools.

At the same time, Eric and Calleigh are investigating a separate case involving a wealthy businessman who had been found dead in his yacht. They discover that the man had been poisoned, and suspicion falls on his wife, who was having an affair. The two cases eventually merge when the team discovers that the businessman's wife had hired the same suspect to rig the nail gun, and she had killed him to cover up the evidence.

The team manages to tie up all the loose ends, and both cases are solved by the end of the episode. The suspect confesses to the murder of Tom and the poisoning of the businessman, and the team is able to bring him to justice.

Overall, the episode keeps viewers on the edge of their seats with a gripping plot that intertwines two separate cases into one satisfying conclusion. With its well-written script, solid performances, and expert direction, Nailed is a must-watch for fans of the CSI Miami series.
