Whether playing a forensic psychologist with an extraordinary gift or a ruthless federal agent chasing after a motorcycle gang, Ally Walker always meant business. After getting her start on daytime television, the actress went on to appear in action films like "Universal Soldier" (1992) and had a memorable role in the blockbuster comedy "While You Were Sleeping" (1995) as the suspicious girlfriend of a comatose man (Peter Gallagher). Walker continued to guest star on hit dramas until she finally scored the lead on the series "Profiler" (NBC, 1996-2000), playing a tormented forensic psychologist who used her analytical skills to solve cases while tracking down a serial killer. She tackled yet another tough-as-nails role on the hit show "Sons of Anarchy" (FX Network, 2008- ) as a vengeful federal agent with sociopathic tendencies. After years of portraying intense characters, Walker displayed a breezier side as a woman trying to balance her life as a single mother and a police detective on the Lifetime series "The Protector" (2011- ), a role where she proved her mettle as one of television's most compelling and versatile actresses.
