CI5, the British squad formed by George Cowley to combat ‘anarchy, acts of terror, crimes against the public’, has developed into an international force with operatives hired from around the world. With connections to the FBI, CIA and other law-enforcement agencies, CI5 operates outside borders with a group of specialists under a similar brief. Their world is a battlefield against terrorists, deadly hit-men, Neo Nazi's, the mafia and diabolical masterminds intent on taking over the world. The Professionals are back!
