George and Martha, a middle-aged history professor and his wife, return home after a faculty get-together. During the party, Martha’s father, the president of the college, had introduced the couple to a new teacher and his wife, and unbeknownst to George, Martha has invited them over for drinks—tonight. As George and Martha sling insults at each other, their wide-eyed guests, Nick and Honey, arrive. At first, the young couple is disconcerted by George and Martha’s bickering, but as the liquor flows, Nick and Honey find themselves drawn into their hosts' tumultuous, damaged world.
