Where to Watch The Visitors (1972)

Every one wants to turn his back on violence until it knocks at his front door.

Bill, Martha and their little child Hal are spending a quiet winter Sunday in their cosy house when they get an unexpected visit from Mike Nickerson and Tony Rodriguez. Mike and Tony are old acquaintances of Bill; a few years back, in Vietnam, they were in the same platoon. They also became opposed parties in a court martial - for a reason that Bill never explained to Martha. What happened in Vietnam, and what is the reason for the presence of Mike and Tony ?
