Max Fortune and Carla Day are agents with the Organization.
Agents is not really the correct word, and 'with' is oversimplification, but more on that later.
Max Fortune is a 45 years old man, a widower for the past twelve years, who has worked hard at his own successful business and being a father of a son who recently graduated college. How that the son, James, has gone off on his own and no serious relationship holds him back, Fortune decides to close down that business to find something he was craving - adventure. He buys a very comfortable camper and heads across the Channel from his native England and heads to warmer climate. It will be in an area north of Naples that Fortune will meet that adventure and then some.
Carla Day is the personification of excitement. Twenty-six years old and raring for all the action life can throw at her, when we first meet her she and a colleague (and sometimes lover) are fleeing from gunmen having just ripped off a drug kingpin. Their shots dispatch the unfortunate workmate but Day survives to fight, literally, another day.
Fortune and Day will become a makeshift pair in an interesting and, for Fortune, fairly ho-hum way. That ho-hum will disappear almost immediately. Nothing, Max Fortune will discover, is ever dull around Carla Day.
The promo blurb for the series sums it as: "Rescued on a mountain road in Italy by Max Fortune, Carla Day involves him in her life of excitement and danger. He becomes hooked on the wealth and glamour surrounding her guardian, known as the Duke, who controls a shadowy business empire [the Organization]. The manipulative Duke uses the steadying influence of Max to tame and protect the wayward girl. He employs Max & Carla on simple missions, as couriers and trouble-shooters for the business. The pair are trouble magnets and adrenaline junkies who face unexpected danger when things invariably turn nasty."
