Season 3

A beautiful synchronized swimmer in an elaborate mermaid costume washes ashore dead, and the clues lead Jim to a bittersweet love triangle and a hip hop mogul trying to turn a mermaid show into multimillion-dollar phenomenon. On the home front, Callie hits a wall in her job search, and Jim realizes the best opportunity for her is the one in Atlanta she passed up to be with him.

While Jim helps Callie settle into her new apartment in Atlanta, Carlos performs a guest autopsy for Daniel's forensics class at Tampa Tech. He discovers that the cadaver he is dissecting is actually a murder victim who turns out to be a student that was killed while participating in an on-campus pharmaceutical study. Also, the Palm Glade substation gets a new addition when FDLE Bureau Chief Jennifer Starke comes down to visit Manus, while Callie gets off to a rocky start with her new boss Dr. Miranda Buckley.

The dead body of a naked woman leads Jim and Carlos to investigate a close­ knit nudist colony fighting against expansion by a luxury condo development. Jennifer begins interviewing the substation employees and finds its high case closure rate seems directly related to Jim, in whom she takes an interest that may be more than just professional.

When Jim finds the ex-Navy Seal owner of his favorite food truck dead in the truck's kitchen, he ends up embroiled in a heated political battle between the new wave of gourmet food trucks and the established boardwalk restaurants. Jennifer takes an active and prying interest in Jim's cases, while Callie's attempt to confront Miranda about her hostility backfires.

Longworth and Jennifer investigate a murder that puts them at odds with the Sovereign Citizens, a bizarre anti-government group that believes they are above the law. Manus and Carlos soon find themselves victims of the Sovereigns' paper terrorism attacks when they are suspended from duty. Callie desperately searches for her old cell phone where she recorded Elkins blackmailing her into sleeping with him for overlooking her tax issues.

When the co-owner of a luxury medical spa turns up dead, Jim and Jennifer investigate the spa's members and discover the high costs the wealthy pay in order to stay looking young and beautiful. Callie gets anxious while both studying for her boards and preparing for her testimony against Elkins. Her house in Palm Glades is falling apart, but her life in Atlanta is picking up.

The body of an $80-million Florida state lottery winner is found murdered on a remote island in Islandia, and Jim and Jennifer must unravel a personal vendetta spanning over a decade between the victim and the island's only resident. Miranda pulls Callie away from her studies to have some fun at a medical sales mixer, but Jim starts to find Callie harder and harder to reach in Atlanta.

On the day of Callie's board exam, Jim must solve the murder of a businesswoman who had founded a new surf clothing line and was about to offer the endorsement opportunity of a lifetime to a young, local surfing champion. Jim gets more frustrated over Callie's lack of communication, while a sympathetic Jennifer tries to comfort him. As he faces an uncertain future where Callie's career in Atlanta will pull her further away from her life with him in Palm Glade, Jim realizes he must make a decision on where their relationship is headed.
