Radio Silence (1970)

RADIO SILENCE A select team of U.S. Army Special Forces Soldiers are sent on a mission to retrieve pieces of a downed U.S. spy satellite from a remote desert region of northern, Mexico. They are excepting a routine, even boring on a mission, asking only "on a Sunday, sir?". What they encounter is the sudden loss of half their team, their Mexican escorts and nearly all of their equipment. They are forced to retreat on foot and spend a long night hiding in a local restaurant trying to understand what they are up against and how to survive with no gear, no support and no time. —Troy Scoughton, Sr.
