Later, Hutton uses the truck in Manhattan for a bogus accident which is a cover for a jewelry store robbery, committed by his accomplice, Maureen. The NYPD cordons off the area because of the warning notices on the truck, but when the head of the chemical company that owns the truck, Dr. Smeat, arrives, they discover the 20 canisters of nitroglycerin have been removed. The NYPD decides to call in the FBI. Jerry Cotton is called onto the case, but suggests to the department chief, Mr. High, that Phil Decker be placed in charge of the investigation. They are told by Dr. Smeat that the nitroglycerin must be kept cool, and that it's packed in ice, but they only have about 30 hours before it becomes unstable. The gangster Larry Link hears about the robbery and has Krusky tortured, but without getting any information. Maureen appears at Link's headquarters and offers to help him find the nitroglycerin for payment. Maureen tells Link that Hutton got his information about where to hijack the truck from Dr. Smeat's secretary, Ruth Warren. Link sends his goons to Ruth's apartment to find out where Hutton is hiding. Cotton and Decker discover the connection between Warren and Hutton, and go to interview Warren. They find her being held by Link's men, and a fight happens. Freed, Warren tells Cotton and Decker where to find Hutton: at his mother's pinball arcade. Cotton persuades Hutton to take, gets hold of the canisters. Link and his men are already at the hiding place, and Cotton is knocked out. When Cotton comes to, he finds out Link has killed Hutton and has the canisters of nitroglycerin. Link then informs the FBI he wants one million dollars for the canisters, otherwise he will let one of them explode somewhere in Manhattan. Link then calls a NYC newspaper with the information about the missing nitroglycerin to put pressure on the government and embarrass the FBI. This causes a panic in Manhattan.
