A team of criminals led by mastermind Peter Branson kidnaps the President of the United States and his two guests from the Middle East, a prince and a king, on San Francisco's Golden Gate Bridge, in a masterfully conceived and clockwork-timed operation. Branson and his men block off both ends of the bridge, wire it with explosives, and demand half a billion dollars and a full pardon for themselves. Any rescue attempts will result in the detonation of the explosives, which will kill the President and destroy the Golden Gate Bridge. However, Branson is an egomaniac, and he cannot resist attention from the media. So he invites the press to stay on the bridge and cover the story. Aware that the FBI will have placed agents among them, he takes the precaution of searching them and removing the armed ones. However, Hagenbach has an ace in the hole: a hand-picked special agent, Paul Revson, who was equipped with only a camera. Allowed to remain on the bridge, Revson sets out to foil Branson's plans and rescue the President. With the help of a doctor and a female journalist, Revson gets a message to his superiors, suggesting various courses of action: supplying drugged food to the terrorists, placing a submarine under the bridge, and trying to neutralize the terrorists' equipment with a laser beam. He also arranges for several carefully disguised weapons and gadgets to be smuggled to him. Working on both ends, Revson, Hagenbach, and those working with them unleash their own carefully conceived plans.
Background
The book was the first of three MacLean wrote set in California. MacLean said in 1976 it was "the best thing I've done."
Reception
The book was a best seller. The Los Angeles Times thought Maclean was "going through the motions". The New York Times thought it was "nonsense, but agreeable nonsense... fun."
In 1975 a film was going to be made by Warner Bros starring Charles Bronson and directed by J. Lee Thompson. However they could not find a script they were happy with. In 1976 Maclean's second wife Mary formed a company with producer Peter Snell, Aleelle Productions, who aimed to make movies based on MacLean novels including Golden Gate, Bear Island, The Way to Dusty Death and Captain Cook. Film rights were bought by Lew Grade's ITC, who announced in October 1977 that the film version would be part of a slate of films worth $97 million. Filming was to begin in February 1978 from a script by Marc Norman and directed by Jerry Jameson. However filming did not take place. In October 1978 ITC announced the film was one of their "contemplated productions." The film was never made.
