The Apocalypse Watch (1995) is a novel by Robert Ludlum. A TV movie based on it aired in 1997 which starred Patrick Bergin and Virginia Madsen. This was Ludlum's second novel to focus on a neo-Nazi conspiracy to take over the world, after The Holcroft Covenant (1978).
Plot
In the Hausruck Hills in Austria, CIA agent Harry Latham attempts infiltrating a secret training airfield belonging to the Brüderschaft der Wacht (The Brotherhood of the Watch), a Neo-nazi movement gradually building a renaissance of the Nazi ideology across Europe. However, he's exposed and captured, and the Brotherhood's chief surgeon, Dr. Gerhardt Kroeger, performs a microchip implant experiment on Harry in an attempt to make him a controllable double-agent.
In Paris, the suicidal act of deranged World War II veteran Pierre Jodelle in a theater draws the attention of Drew Latham, Harry's younger brother and an agent for the United States Department of Consular Operations, whom believes Jodelle might have uncovered a potential Neo-nazi network in France, being his best clue to find his missing brother. After suffering an attempt on his life, Drew is put under the protection of the Deuxième Bureau under Director Claude Moreau, on a request from Drew's superior officer, Director Wesley Sorenson. As Drew continues his investigation, he's also assisted by Stanley 'Stosh' Witkowski, a Cold War veteran and Chief of Security for the US Embassy in Paris, and Karin De Vries, a linguistics expert and records specialist (and an unofficial black ops agent). Sudden and unexpectedly, Harry makes contact with the CIA weeks later, providing an explosive, suspicious incriminating list involving high-profile personnel, from politicians to celebrities, that he acquired under the alias 'Alexander Lassiter' - In fact, this is a move by the Brotherhood itself to provoke discord amongst the world's nations, removing strategic personnel to be replaced with the Brotherhood's homegrown sleeper agents, the Sonnenkinder, who'd "pave the road for the Fourth Reich". Drew and Harry meet each other at the Paris airport, but suddenly are targeted by the Brotherhood's assassins in a blitzkrieg attack. Though Drew survives, Harry is a confirmed kill.
Moved by grief, determined to avenge his brother and draw the Brotherhood's agents into the open, Drew decides to assume Harry's identity, leading to believe he survived the attack. The fact that Harry's corpse could be recovered in time and couldn't be identified by the assassins whom rashly left the scene only strengthens the scenario, drawing the concern and even desperation from Kroeger, fearing his microchip experiment (which has an expiry date that'd result in the chip's detonation) would be exposed. Kroeger dispatches a unit of elite assassins - the Blitzkrieger - to neutralize Drew, but he and Witkowski repel the attempts, to the point the Blitzkrieger, fearing execution for their repeated failures, desert the Brotherhood and go into self-imposed exile in Argentina. Kroeger is eventually captured afterwards and taken to interrogation, but becomes unable to produce much relevant information.
Drew's investigation into Kroeger's contacts, the Blitzkrieger attacks and the repeated attempts on his life reveal an informant network within the U.S. Embassy, which is eventually revealed to be headed by Janine Clunes Courtland, a Sonnenkind agent implanted years ago and wife to U.S. Ambassador Daniel Courtland. As Drew, Witkowski, De Vries and even the Deuxième attempt following her steps, to much little avail, Moreau and Sorenson perform their own investigations into both Clunes and Kroeger's connections, they come across the name of Dr. Hans Traupman, a neurosurgeon whom is a close friend of Kroeger, and has shown to have a connection with the Brotherhood. When Clunes is reunited with her husband (a devised plan to attempt reaching her), she is killed in a sudden strike by the Brotherhood's assassins whom quickly escape again. Witkowski, in an attempt to root out the Brotherhood's agents, forces Moreau to secret away her corpse and deliberately lie to the press that she survived the assault. Moreau himself, after an assassination attempt on his life, eventually confesses his involvement as a double agent for the Brotherhood, using their money payments for a secret revenge plan of his own making, which will be exposed if Moreau decides to interfere. Sorenson orders a black ops operation to kidnap Dr. Traupman and bring him to France for interrogation.
