From the liner notes

This TV series documents the stories of six individuals from whose powerful addictions nearly ruined their lives. Alyson was a gifted student and former White House intern until her dependence on alcohol and drugs nearly destroyed her dreams. Vanessa was once a successful actress before compulsive shopping drove her to bankruptcy and despair. Gabe is a gambler who has lost over $500,000 and his home, and Matt was addicted to crack-cocaine. This season also tracks the interventions of two meth addicts: Sara, who must save herself for the sake of her daughter, and former rock star Travis, whose early fame resulted in drug use.
