It's 1975, and the North Vietnamese army is poised to roll into Saigon. As the city falls into chaos, two lovers make their way across the city to escape to a new life. Helen Adams, an American photojournalist, must take leave of a devastated country she has come to love. Nguyen Pran Linh, the man who loves her, must deal with his own conflicted loyalties. As they race through the streets, they play out a drama of love and betrayal that began twelve years before. Their mentor, the larger-than-life war correspondent Sam Darrow, was once Helen's infuriating lover and fiercest competitor, as well as Linh's secret keeper, protector, and truest friend. As the sun sets on their life in Saigon, Helen and Linh struggle against both their inner demons and the ghosts of the past, illuminating the horrors of war, the dangers of obsession, and the redemptive power of love.
