When his rich grandfather, Howard Red Stevens, dies, Jason does not expect to inherit anything from his multi-billion-dollar estate. He strongly resents his grandfather because his father had died while working for him. There is an inheritance, in fact, but it comes with a condition: Jason must complete 12 separate assignments within a year in order to get it.
