Perhaps you took note of the History Channel series, "Hunting Hitler." It ran for three seasons on that channel, and pursued the line that there were various methods by which Hitler could've exited the Third Reich, how there was infrastructure in place, etc. One of the most interesting aspects was the detailing off safe houses, bunkers and even weapons development in Argentina.
Like most History Channel programming, long on hyperbole and leaps in logic, but entertaining. The Argentina stuff got me to sit up and pay attention. Fascinating.
