Former serviceman Monty Brewster learns that a wealthy unknown uncle has died, leaving him eight million dollars. A stipulation in the will demands that he spend the first million in just two months or forfeit the entire inheritance. Desperate to get rid of the money, he starts businesses and makes deliberately bad investments, but things go awry as the ventures begin earning rather than losing money.

When a scientist runs out of funding for his life-saving medical research, he accepts an investment from a shadowy military organization to finish his work. But in return, he is forced to use his new technology to create the ultimate battlefield weapon - a full size Tyrannosaures Rex, who is ready to break free and start the ultimate battle with the human race.
