The Visitors

"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 ?
