Two fishermen find her but then are soon killed off by a group of suited corporate agents who ride out in a speedboat because they were witnesses to the crash.

In New York City, an American investigative reporter, Moses Brody (James Franciscus), receives a phone call from his ex-wife Nicole (Mag Fleming), who runs a local restaurant in Martinique, who tells him about an "important story".

Later that evening, while wandering the streets of the town, Brody is attacked by a gang of thugs but is rescued by a mysterious local man named George, who owns a fishing trawler and tells him that Nicole was a friend of his and she was killed because she knew that the crashed Concorde flight landed on a reef nearby and the two of them decide to investigate.

Later, they arrive at the crash site, and after donning scuba gear, they find the wreck of the Concorde submerged under 100 feet of water in the Caribbean.

Moses discovers explosive charges on the downed plane, which were planted earlier by Milland's henchmen to destroy any evidence of foul play.

Brody outwits them by hiding in an underwater cave, in which he goes back to the surface, pulls out the henchman who remained behind in the speed board, and stole it.

Concorde plane lands in Rio de Janeiro, Brazil which prepares itself for a flight from Venezuela to London.

After reaching the shore, Brody tries talking to Jean about the crash, but she is so shaken by the traumatic experience that she can't remember very much.

But soon Milland's henchmen, led by Forsythe (Venantino Venantini) find Brody and Jean again and give chase, but they are cut off by a construction vehicle.

Up in the cockpit, the pilot Captain Scott (Van Johnson) discovers something which same thing happened as with the first attack: loss of power.

On the ground, Jean contacts the American Consul at a bank, but Forsythe and his henchmen arrive again, and she and Brody must run.

The next day, Milland contacts Brody by phone and wants to offer him a shady contract after reading the headline "Concorde Passengers Saved by Journalist."

He says he wants to know the heads of the top corporations in New York City, heavily involved in aircraft sales to South American countries, specifically those most hurt by competition from Concorde.
