The Season 20 finale of this venerable police procedural, "End Game," opens with a teenager whose corpse is found in the Hudson River. A frustrated Lt. Benson (Mariska Hargitay) trusts her strong intuition that NYPD Attorney Rob Miller (recurring guest star Titus Welliver) is behind this unexplained death, but she has no way of proving that. Although the case hinges only on circumstantial evidence, however, Assistant District Attorney Stone (Philip Winchester) decides to take the case to court before Miller ruins even more lives. Callie Thorne also guest stars.
