ABC has followed four American families over the past year as they deal with the daily challenges of teen pregnancy and parenting. The show, airing at 10 PM EST, also explores two types of teen sex education programs: a sex education class in Massachusetts that discusses abstinence and the value of sexually active teens using contraception, and an abstinence program based in Texas.
