The film "Hulk" (20 films) grew into a lonely Bruce Banner (eric bana), and became a scientist in the Berkeley Army of the United States, specializing in the research of using nano-robots to treat human bodies. He falls in love with Betty Ross (Jennifer Lynn Connelly), the daughter of General Ross. Bruce, whose career and feelings are smooth, seems to have got rid of the shadow of childhood loneliness and embarked on an enviable road to success. ? However, the good times did not last long. In an experiment, in order to protect a colleague, Bruce shielded his body from deadly gamma rays, and the mysterious power in Bruce was unexpectedly awakened. From then on, whenever he gets emotional, Bruce will lose his self-awareness and become a Hulk, with super destructive power and will resistance. But Bruce doesn't know and doesn't want to know his extraordinary transformation ability. For him, he is just a lonely scientist with no past and full of confusion, and he can't understand why he suddenly attracted the military to round up. ? In the face of a series of unexpected events, Bruce's girlfriend Betty Ross also felt confused and helpless. She wanted to help Bruce, but she was stopped by her father who was in charge of rounding up the Hulk. At this moment, David (nick nolte), a mysterious figure who claims to be Bruce's father, appears beside General Ross. He warned Betty not to go near his son, which made Betty more confused. In order to protect her, Bruce had to deal with the "killer" sent by his father-the mutant dog. In order to gain strength, his father himself was irradiated by gamma rays. Although he didn't become a green monster, his body has also changed, and he can absorb the energy of the surrounding objects and melt into them. ? Finally, the father and son confronted each other, and the Hulk asked the invisible man and the father for his son's energy, but the son didn't give it at first. Later, he came up with a clever plan and gave all his energy to his father. Because the father absorbed the energy of his son and the energy of the surrounding objects, the body energy was supersaturated and the strength decreased. In order to destroy his father, the military used gamma bullets, which sacrificed Bruce's life and caused a big explosion. Bruce's whereabouts became a mystery. ? At the end of the film, in a primitive jungle, a doctor is treating a poor tribe. At this time, a group of mercenaries came and took him away. The mercenary leader saw the local doctor Bruce Banner and told him to leave. Instead of leaving, the doctor said, "You'd better not provoke me, because you don't want to see me provoked."
