The human will to survive can't be underestimated. That's the mantra of this week's Team Never Quit guest, Kara Chamberlain. While watering plants in the front yard of a friend's house, Kara was kidnapped at gunpoint by a serial killer. She was only 15. Making mental notes of every detail along the way in her abductor's car - from memorizing the serial number of the large storage bin he forced her into to counting the turns he made, the music he played, his Marlboro Red cigarettes, details from within his apartment while handcuffed and gagged, Kara used every bit of it to her benefit. She not only escaped after 18 hours, but the details she recalled helped catch him. Kara's case also helped police link the killer to three unsolved murders in other states.

These days, Kara's life is dedicated to spreading hope and strength to other survivors.
