Chapter 1: Ambush

Amy and Mike have always been inseparable siblings. But after Mike got drafted to fight in Vietnam, it's not only Amy who acutely feels his absence - his pregnant wife, Laura, also misses him dearly.

Amy copes by writing and burying herself in her summer job and her own dream world. But, this tomboyish loner is growing up at the same time, starting a relationship with budding musician Jeff, who's got his own trouble to contend with.

Meanwhile, in Vietnam, Mike battles with both physical and psychological enemies while protecting an orphaned girl.

In this stirring drama of growing up, falling in love, and of the innocent victims of war, family remains at the center.
