Fathom

Fathom Harvill is in Spain with a U.S. parachute team. She agrees to accept a lift from a man named Timothy who then takes her to see Douglas Campbell. Campbell hints that the mission involves recovering a triggering device for a missing nuclear weapon.

Campbell claims to be a British agent working for NATO and asks Fathom to help locate the trigger hidden inside an ancient Chinese figurine called the Fire Dragon. He explains that the device is missing in the Mediterranean region and could have international consequences. This briefing sets the stage for a high-stakes pursuit.

Following Campbell's plan, Fathom skydives into the villa of Peter Merriwether. She discovers a dead body and is immediately seized by Merriwether, who accuses her of murder. The danger escalates as she realises she has stepped into a complex web of deception.

Merriwether questions Fathom and reveals a staggering twist: the nuclear weapon story was a ruse. He asserts that the Fire Dragon was stolen from a Far East museum by a Korean War deserter, and that Campbell is the deserter. He also confesses that he is a private investigator.

Across the chase, Serapkin, a wealthy Armenian private collector, also competes to obtain the figurine. He is another formidable rival in the race to control the Fire Dragon.

Fathom fends off a knife attack and a harpoon attack during the Villa sequence. She locates the Fire Dragon concealed inside her makeup case. The discovery sharpens the cat-and-mouse game with multiple factions closing in.

Campbell tries to reassert his trustworthiness and accuses Merriwether of desertion. Fathom processes the conflicting claims, still uncertain who to trust as danger looms.

Fathom boards a plane with Campbell and Timothy, and they immediately attempt to toss her from the aircraft with a defective parachute. The flight becomes a trap as the would-be killers seek to eliminate her midair.

Merriwether catches up with them in another plane, and the pilots engage in a tense aerial duel over the sea. The confrontation tests skill and nerve as one pilot tries to force the other down.

In the mid-air confrontation, Merriwether shoots Campbell dead. The sudden loss shifts the balance of power and leaves Fathom to reassess loyalties.

Timothy draws a gun and Fathom fights him, causing Timothy to fall from the plane. The would-be traitor is eliminated, clearing the way for Merriwether's plan.

With Campbell dead and the stake high, Fathom tosses the Fire Dragon down to Jo-May Soon to return it to China as part of a negotiated outcome.

Merriwether uses the leverage of Fathom's passport to press for a meeting, and Fathom agrees to meet him later in a bar to sort out the remaining terms.
