Rollercoaster

A young psychopathic bomber causes terror at American theme parks by placing homemade explosives on tracks, leading to derailing roller coasters and deadly consequences. When safety inspector Harry Calder is called to investigate, he suspects a connection between two incidents at different parks and infiltrates a meeting of executives in Chicago. A cat-and-mouse game ensues as Calder must deliver ransom money without triggering another bomb, while also racing against time to prevent further attacks on popular roller coasters.
