A multi-generational saga of passion, vision, and the legacies of a family business operating in every continent on the globe. Engineer Tristan Flynn sets the story in motion when he meets and marries young Marlena Sanchez while traveling through Spain as a backpacking undergrad, eventually establishing Flynn Enterprises, a multi-billion dollar engineering firm. The series follows the lives and loves of their offspring, business colleagues, and descendants, each of whom brings their own passions to the Flynn dynasty, crisscrossing oceans, continents, and racial boundaries.
