S16, E4: New York City bike messenger Holden March (guest star John Karna) creates a video diary of his troubles with women. Talk soon escalates to action, and the SVU scrambles to find his manifesto before he commits another violent act. When Rollins (Kelli Giddish) and Amaro (Danny Pino) come face to face with Holden, they find out just how dangerous a desperate man can be. Meanwhile, as Benson (Mariska Hargitay) balances the responsibilities of motherhood and career, the new Deputy Chief of SVU (guest star Peter Gallagher) calls her leadership into question.
