Haunted by the monster inside him, Dr. Bruce Banner lives in hiding, trying to find a cure for the gamma radiation that transforms him into the Hulk whenever his heart rate spikes. While lying low in Brazil, Banner secretly works on a cure with the help of an anonymous scientist known as Mr. Blue, but when the U.S. military—led by General Thaddeus “Thunderbolt” Ross—tracks him down, a chaotic chase begins. Banner flees back to the U.S. and reunites with his former love, Betty Ross, the general’s daughter. Meanwhile, obsessed with capturing the Hulk, General Ross recruits Emil Blonsky, a soldier who undergoes experimental treatments to gain enhanced strength. But Blonsky’s hunger for power transforms him into the monstrous Abomination. As destruction rips through Harlem, Banner must embrace his alter ego to stop Abomination. In the end, Hulk emerges victorious but disappears once again, determined to stay hidden while still searching for control over the beast within.
