Where to Watch Twilight's Last Gleaming (1977)

We have invaded Silo 3. We are prepared to launch nine nuclear missiles. We demand ten million dollars, Air Force One... and you, Mr President.

A renegade USAF general, Lawrence Dell, escapes from a military prison and takes over an ICBM silo near Montana and threatens to provoke World War 3 unless the President reveals details of a secret meeting held just after the start of the Vietnam War between Dell and the then President's most trusted advisors.
