Bruce Banner has something haunting him, something he would wish to control if not entirely shake off. It's destructive as well as indestructible, a monster of sorts.
He had said, "You wouldn't like me when I'm angry" and no statement could be more true.
Bruce Banner turns green and many times his own size, becomes a hulking Behemoth of unimaginable strength, when he is provoked to extremes; and destruction always follows.
Hidden away in Brazil, away from the American military which would like to control and exploit him and his powers, Bruce searches for the antidote for his curse: Both scientifically and in self-control: Close, but to no avail.
Soon, the American authorities catch up with him. He flees, soon finds himself back in America; and back in the arms of Betty Ross, his long lost love he wasn't certain he'd ever see again. Her father, General Thaddeus Ross, is the one who would like to capture Bruce and exploit his powers.
Meantime Bruce and Betty locate a scientist, Dr. Samuel Sterns, whom Bruce had been secretly communicating with on the Net, who is willing to help him with the antidote.
All the while, a gung-ho veteran soldier under the command of General Ross, has his eyes on obtaining the great powers of Bruce's alter ego Hulk. With the help of the general and the scientist, this over-zealous soldier is transformed into a huge, spiked monster that seems to outmatch the Hulk.
Without spoiling too much of the plot, I think I'll stop there and proceed to the deeper undercurrents of the story.
