Law & Order: Special Victims Unit: Ripped

Luke, the suspect in the attack of a fellow high school student, becomes angered during an initial interview and punches Detective Fin. Later, at the station, Luke can't remember anything that happened. Complicating matters is that Luke is the son of Stabler's former partner and Stabler gets suspended after he tries to help out. Steroids are found in Luke's gym locker and his father attacks him. Stabler steps in, beats him down and immediately goes to a psychiatrist for help with his own rage. Luke gets ahold of his dad's gun, shoots him and goes to the house of the girl he attacked.
