Sergeant Bett Smythe and Lieutenant Gale Rains are building a life together, despite the risks in the tightly closeted world of the Women's Army Corps. When another couple, Captain Kathleen Hartley and Lieutenant Victoria Whitman, invite Bett and Rain to a dinner party, they're introduced to the lesbian underground on the base.

Kat and Whit have had a turbulent relationship, and as a budding friendship deepens, Kat's attraction to Rain threatens both couples' futures. When Whit's friend is accused of sexually assaulting a recruit, the ensuing investigation impacts them all, professionally and personally.

As the Battle of the Bulge rages overseas, the bounds of love and friendship are tested. Whit will do almost anything to preserve what she has with Kat, but who is the real threat? And can Bett protect her relationship from the very real dangers close to heart and home?
