This was one of the best episodes I've seen on Without A Trace. The storyline was absolutely amazing, it lets you in to a woman's life as she struggles to lead one that you and I take for granted. It shows a glimpse of how a mental illness affects everyone. Her mom, her brother and especially her. The actress did a wonderful job portraying the hopelessness, frustration, and despair of bipolar disorder. I would recommend this episode for anyone, especially those with interests in psychology.
The ending scene is the most touching, and will most definately make people cry. I know I did.
