A former CIA agent reveals shocking new evidence suggesting Hitler may have faked his death and escaped to Argentina, where Nazi plans for a Fourth Reich could have been in the works.

A former CIA agent believes there is growing evidence that Adolf Hitler faked his own death and escaped to Argentina, where "followers tried to reboot his fallen Nazi empire," the UK-based Daily Mail reported on Sunday.

The agent, Bob Baer, believes that the official version of history, where Hitler committed suicide in Berlin on April 30, 1945 might need "rethinking once anticipated bombshell evidence is released."

Baer is expecting a set of documents out of Argentina to reveal "possible entanglements between the fascist dictator" and Argentina's government "that may have been hiding him."

Baer believes these archives, which include details on Nazis who fled to Argentina after World War II may indicate the existence of efforts to build a Fourth Reich in Argentina, as well as implicate Argentinian officials in support of Nazis, money laundering schemes, and more, the Daily Mail reported.

He is also expecting to unveil a link between then-Argentinian president Juan Peron and the backing of a 1950s nuclear fusion lab headed by a Nazi scientist on on Huemul Island, near Bariloche, the Daily Mail added.

"The ex-CIA agent thinks it's possible there were legitimate attempts at a Fourth Reich with plans including a nuclear weapon strike on Manhattan," the Daily Mail report stated.

Baer commented that the documents will likely include a paper or money trail indicating that the Argentinian government at the time was involved in the construction of a possible Nazi hideout in Argentina's Misiones province which was uncovered in a 2015 archaeological dig.

He added that the Misiones discovery is the "most interesting find" related to Nazis in Argentina so far.

"Lots of money was spent on a compound with plumbing and electricity in the middle of nowhere," Baer told the Daily Mail, and added that Nazi memorabilia, including German World War II-era coins, was found in the area.

"If you were going to hide Hitler, that's where you'd do it," he claimed.

While history believes that Hitler, and his wife, Eva Braun committed suicide in Berlin in April 1945, senior Nazi figures, including Adolf Eichmann and Josef Mengele are known to have fled to Argentina.
