Computer whiz-kid Peter Keithly, asked to transfer a betting formula onto computer tape, dies shortly afterwards. An old friend of his, Jonathan Perry, finds himself in possession of the tapes, and also discovers that there are greedy, desperate men who will do anything to get their hands on the lucrative software. The evil, bull-faced Angelo goes too far and ends up in jail. Fourteen years later he's free, and very keen not only to get hold of the tapes, but also Jonathan Derry.
