Ignoring his 2-S selective service deferment, Conor Patrick McKall volunteers for the draft, and Uncle Sam promptly deposits him in the Big Green Machine.

Six months later McKall is walking point in jungles, rice paddies, and rubber plantations. In nine short months, he's made an infantry squad leader responsible for a dozen other grunts. In the "boonies," life is lived one day at a time.

Joining McKall's squad is Jack "Red" Sheridan whose near-death encounter with a black panther presents challenges to his credibility from other members of Lima Platoon. When McKall stands with Sheridan, an unbreakable bond develops. They meet Red Cross Donut Dollies and together experience the infamous Black Virgin Mountain where the good guys control the top and the bad guys the rest.

Escaping Vietnam for a handful of days on R&R in Sydney, Conor experiences Aussie hospitality and the attention of a green-eyed beauty who offers him a chance to escape the war. Loyal to his oath and to his men, Sergeant McKall barely has time to supplant the fading scent of Chanel before he and his squad must face their determined and deadly adversaries. The arbitrary gauntlet of Vietnam offers no guarantees.
