The Professionals

Charles Nesbitt, an expert on chemical weapons, threatens to contaminate the water sources of London with a lethal hallucogenic drug and in order to back up his claims, plans several small 'demonstrations' in warning to the local authorities - including CI5.

An Iron Curtain agent is using a young girl to extort secrets from, and ultimately destroy the career of, a future British Prime Minister, unaware that the girl is the long-lost daughter of a well-known local prostitute.

A gangster called Turkel devises a plot to free his brother from jail by taking hostage an important figure in authority. He is unaware, however, that the 'important figure' he has taken in is actually Cowley masquerading as the Home Secretary, with Bodie as his bodyguard and Doyle ready to pull the trigger on Turkel's brother.

CI5 become aware that an assassination plot on a group of visiting Greek Royals is being planned using a rifle that has a range of over two miles. But they must find out who is the gunman and what is his target - before it is too late.

When a newspaper takes it upon themselves to irresponsibly publish a list of the names of witnesses to an assassination, it is left to CI5 to not only protect these people, but at the same time apprehend the killers before they strike again.

A group of former comrades from Bodie's mercenary days reappear in England and in order to impress a top London gangster, carry out a violent raid on a local bank. It's left to CI5 to catch and stop the ringleader Krivas and his gang, reuniting Bodie with some of his old adversaries in the process.
