In this comedy a sneaky salesman tries to sell an inventor's newest product, a water-based fuel. Before the inventor can finish testing the product he needs cash, so the salesman desperately endeavors to come up with some by creating a phony stock promotion. When he announces that the great invention has finally been perfected, investors begin handing him money hand-over-fist. The salesman then uses the cash to create a phone corporation complete with a fake board of directors. Just as their success seems assured, the inventor is abducted. The salesman must then find him or end up in prison. ~ Sandra Brennan, All Movie Guide
