Law and Order: Special Victims Unit: Maternal Instincts

S17 Ep6 While Rollins' mother (Virginia Madsen) throws her a baby shower, the Svu is called to a hotel after a violinist is raped by her flautist colleague, Anton (Zach McGowan). The man has no recollection of his wrongdoings and claims he was drugged and robbed by an escort. When the security tape arrives, Rollins sees that it was her fugitive sister, Kim (Lindsay Pulsipher), who stole Anton's flute, leading her to have to track down her sister before Benson and Tutuola find out her secret. Meanwhile, Deputy Chief Dodds introduces his son, Mike (Andy Karl), as SVU's new sergeant.
