A killer is stalking high-priced escorts and leaving a trail of bodies in empty mansions along Miami Beach's intracoastal waterway. When the crimes become too much for the locals to handle, FBI Agents Kate Walsh and Declan James must find a killer walking among the city's elite. Amid the glamour and money is a seedy underbelly that runs through the city like an electrical current. Young women are enticed into relationships with older men where sex and money are traded—creating a power dynamic that leaves the woman vulnerable and susceptible to a killer. Agents Walsh and James must figure out who to believe in a city where everyone has an agenda, and even the local cops seem to have something to hide. A devastating break in the case reveals the potential killer, but the chase is on to find out who is harboring and potentially helping him. Can Agent Walsh use her profiling skills to figure out his plan before the next victim is found or will terror keep reigning in the city?
