After fleeing a Nigerian operation blown apart by the sudden and unexplained non-cooperation of his U.S. contact, Westen finds himself in his hometown of Miami, Florida, attended to by his ex-girlfriend, Fiona Glenanne, but abandoned by all his normal intelligence contacts, under continuous surveillance with his personal assets frozen. Extraordinary efforts to reach his U.S. government handler eventually yield only a grudging admission that someone powerful wants him "on ice" in Miami; if he leaves the city he will be hunted down and taken into custody, whereas by staying there he can remain relatively free. Consumed by the desire to find out why he has been burned, and by whom, Westen goes to work as an unlicensed private investigator/spy/soldier of fortune for anyone in town who can pay him any money in order to fund his personal investigation into his own situation as a blacklisted agent. Throughout the series Westen battles and outwits an array of mobsters, con artists, contract killers, professional thieves, drug traffickers, sex traffickers, deadbeat dads, arms dealers, kidnappers and war criminals. The series makes frequent use of jury rigging, with the characters improvising devices to do the job of more expensive, harder-to-obtain items.
