[2] Bull Webster is a taxi driver with some work problems on his hands: the Spider Corporation, a giant financial holding company, has decided to buy out his taxi co-operative in order to make it go bankrupt and purchase its land at a low cost.

Bull is almost driven to desperation, but then he finds the winning ticket in his pocket to a lottery with the biggest prize of all time: $150 million!

But at this point, Bull's future begins to interest those responsible for the destiny of human affairs: Heaven and Hell send an Angel and a Devil to tempt Bull into evil or to convince him to do good.
