Lockheart Industries are looking for a new product to make them huge sums of money. Their whizz-kid Philip comes up with the superb idea of designer air - Perrier for the lungs, in the form of their patent-pending Suck And Blow machine. For a while, all is well, and the machines are a huge success, as sales massively exceed all projections. But greed forces up the price of air until the oxygen industry becomes privatised. And if you can't afford to pay, you have no right to live. Philip's conscience ultimately wins through at the end of the day, and he takes extreme measures to rectify everything he feels he has destroyed (and wreck the Suck And Blow machine).
