Investigating a porn baron, Crockett and Tubbs become involved with an undercover FBI agent who may have gone native and become a criminal, and may have murdered an underage porn starlet. Meanwhile, Zito and Switek pose as fences, and Elvis the crocodile feels unloved!
In court, Crockett refuses to identify an informant and spends more time in jail than the drug dealer he is trying to bust. Gina and Trudy infiltrate a prostitution ring. Gina is placed in a compromising position when they are suspicious that she is not a hooker.
Someone in law enforcement is murdering drug dealers and their families in cold blood. To find the culprit, Crockett and Tubbs go undercover and travel to Colombia with a laid-back pilot to pose as dealers.
The squad is assigned to assist Robbery with a string of brutal home invasions. Castillo is concerned the officer in charge - who was Crockett's mentor - is mishandling the investigation and the two clash, leaving Crockett torn between loyalty and a resolved case.
