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.

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".

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.

The evidence recovered plus intelligence analysis and Drew's quick deduction has them discover that the Brotherhood is using glider aircraft to carry out the chemical strike, as they would not be easily spotted on radar and be untargetable by anti-air missiles.

With the aid of two hired prostitutes whom were spending the night at the place, Drew and his team are able to neutralize all resistance, but discover in shock when encountering Monluc, in a comatose state, seeing his facial features match exactly those of Adolf Hitler, under a very advanced age.
