One man and his computer take on a ruthless multi-national conspiracy in the classic TV techno-thriller. Henry Jay is a man without any noticeable flair - a stamp collector who expects to spend his working life in the Department of Commercial Development, earning occasional promotions and regularly catching the 6:15pm from Waterloo to his nice semi in the suburbs. But in compiling a long and boring report on "Computer Fraud in the Age of Electronic Accounting", Henry begins to uncover a vast and corrupt network of businessmen and politicians. There are, as Henry soon discovers, many reasons to ignore the matter - a rising body count, a link to British intelligence and a threat on his own life. But armed with just a computer and a civil servant's tenacity, Henry picks up the trail and pits himself against a nebulous, cold-blooded enemy.
