ADA Kibre works with Detectives Stabler and Benson to prosecute a serial rapist Gabriel whose trail of victims through the years has been whitewashed by his wealthy and protective mother Eleanor. Kibre must also overcome witness intimidation – and even sees her crucial DNA evidence tossed out – but the slippery suspect's lawyer has yet another surprise under his sleeve.

The crossover starts on Law & Order: Special Victims Unit S06E20 Night (I).
