Rollercoaster: A Thrilling Mystery

An unnamed man sneaks into Ocean View Amusement Park and places a small radio-controlled bomb on the tracks of the park’s wooden roller coaster, The Rocket. The bomb detonates, causing the ride’s train to derail, killing and injuring the riders as a result. Safety inspector Harry Calder, who initially cleared the ride, is called to the park to investigate. A park worker tells Calder that he saw what he thought was a park maintenance man up on the tracks earlier that day but did not state that the man was someone other than the park had authorized to be there.

A Series of Attacks

The bomber causes a fire on a dark ride at another park in Pittsburgh. Calder suspects the incidents might be linked, and learns that the executives of companies running the largest amusement parks in America are holding a meeting in Chicago. Calder flies to Chicago and intrudes on the meeting. One of the executives plays a tape sent by the bomber, wherein he demands $1 million to stop his activities.

A Deadly Game

Back home, Calder is visited by FBI Agent Hoyt, who says the extortion money is to be delivered by Calder at Kings Dominion. There, Calder is ordered to wait at a telephone, and the bomber calls, warning him there is a bomb in the park. He sends Calder a two-way radio so that he can keep contact, then orders Calder to go on various rides in the park, such as the Rebel Yell roller coaster. While Calder is riding on the Skyway, the bomber tells Calder that the bomb is located in the radio. He warns Calder not to throw it away, because it will explode on impact on the paths below, which are occupied by many of the park’s visitors. He orders Calder to falsely signal that he has made the delivery in order to distract the FBI, then leave the money on a bench. Calder complies and walks away. Later, Hoyt admits that he marked the money (violating the bomber’s instructions). Calder demands to be sent home and leaves the bomb radio with the bomb squad.

The Final Showdown

Back home, Calder gets another call from the bomber. He blames Calder for the marked money and threatens another attack. Assuming it will be directed at himself personally, Calder deduces that the next target will be Revolution at Magic Mountain. The FBI rejects Calder’s hypothesis but decides to investigate anyway because the ride is scheduled to debut on July 4, when park attendance will be at its highest for the season. Agents disguised as park maintenance men eventually find a bomb attached to the tracks and disarm it.

The bomber returns to his car and gets a new bomb just as the Revolution is about to open. In order to get on board, he pays a park guest $100 for his “Gold Ticket”, which entitles the holder to be one of the first passengers. He places the bomb under his seat in the rear of the train. Following the inaugural ride, Calder recognizes the bomber’s voice during his ride exit interview with a reporter. He chases the bomber and alerts the agents that he might have placed something in the coaster train. The train leaves the chain lift on its second ride through.

The bomber is eventually cornered and threatens to blow up the ride, holding the detonator in his hand while the agents try to jam the signal. He demands a firearm. Calder takes one from an agent and begins to hand it to him. Agents succeed in jamming the detonator’s signal and alert Calder. Calder retains the gun but in doing so accidentally shoots the bomber, who then runs away. He hops a fence into the area below the Revolution and runs blindly, eventually circling back toward Calder. The bomber climbs onto the track but sees Calder and freezes. He is hit and killed by the coaster train. The ride reopens following the accident.
