A young man is found dead in the Village. Evidence lead Benson and Stabler to the guy's boyfriend and the boyfriend's father (George Segal) - an anti-gay doctor with radical theories on homosexuals. We learn that the father caught the two men together in bed, killed the boyfriend and dumped the body. But the son, feeling guilty for causing his dad to go to such lengths, confesses to the crime. Novak knows the son is protecting the father and does an amazing job in court - with a little help from guest star Fred "Branch" Thompson - tearing down the case of the defense attorney (guest star Michael Boatman), finding a surprise witness and getting the father to admit his crime.
