Beauty and the Beast

Detective Catherine Chandler is a homicide detective with a partner named Tess. A long time ago, Catherine saw her mother get murdered by two gunmen who would have killed her as well, but something stepped in and saved her life. While investigating a recent murder, a clue leads Catherine to Dr. Vincent Keller, a man who was supposedly killed in 2002 serving in Afghanistan. It ends up that Vincent is alive, and he's the same man who saved her. But he's been in hiding for the last 10 years because his condition leads him to turn into a beast when he becomes enraged. Once meeting with him, Catherine makes a deal: she'll keep his secret if he can help her with her mother's murder. Their partnership continues to grow and, of course, the pair find themselves drawn to each other.
