Incredible Hulk Jack McGee is an intrepid reporter for the National Register, a sensational newspaper beneath his dignity. He’s always trying to gain an interview with scientists David Banner and Elaina Marks, but they think he’s a low-grade rag. Then a group of women witnesses the creature, and McGee follows them to the laboratory to see their report. He’s soon convinced the boffins are experimenting in human strength enhancement, but when Banner is subjected to another hypnosis session, the resulting Hulk-out destroys the lab.
The next day, the Hulk smashes through a police car and escapes. Then a bomber, Ray Floyd, starts to target Westco oil stations, including one near the Marks’s home. As McGee interviews Westco employees, he discovers that Floyd’s father died when his gas station was bombed, and that the younger Floyd blames Westco for the tragedy. As the story develops, McGee suspects that the Marks and Floyd are connected to each other.
An informant tells Jack about an international mercenary named LaFronte, who has taken a job at Limelight magazine to ruin The Register. The intrepid reporter isn’t impressed, but when he phones a friend at Limelight, Pauline, she tells him that LaFronte is after a dummy lab at the Register. McGee investigates and soon discovers records of shady dealings by the mercenary all over the world.
A tip leads McGee to a bar that was damaged in a Hulk rampage. But when he questions a crippled man, John Doe, about the incident, he realizes that he’s merely a spokesman for the handicapped. McGee follows him to a posh mansion, but when the Hulk crashes through the door, it reveals a jewel thief.
A rumor spreads that the Hulk has been seen at an archaeological dig on a tribal reservation, so McGee goes to the museum to get a first-hand account from curator Prof. Williams and a local Indian Chief. When the Hulk rampages through the museum, however, the Professor explains that the brute is an ancient spirit enraged by intrusion on tribal land. Afterward, Williams’ assistant Dr. White insists that the Hulk is nothing more than an ordinary specimen of the Creature race.
