When Richard Chapman offers to host his younger brother's bachelor party he expects a certain amount of debauchery. He sends his wife, Kristin, and his young daughter off to his mother-in-law's for the weekend and he opens his Westchester home to his brother's friends and their hired entertainment. What he does not expect is this: bacchanalian drunkenness, a dangerously intimate moment in his guest bedroom, and two naked women stabbing and killing their Russian bodyguards before driving off into the night.
