When film tycoon, Sir Robert Hellier, loses his daughter to heroin, he declares war on the drug pedlars. London drug specialist, Nicholas Warren, is called in to organise an expedition to the Middle East, in an attempt to track down the big-time dope runners, inveigle themselves into their confidence and make them an offer they can't refuse. No expense is spared in the plans for their capture, but with a hundred million dollars worth of heroin at stake, the 'spoilers' must use methods as ruthless as their prey.
