War is raging. Lieutenant Ben Kinkaid of the US military police is patrolling the chaotic streets of Saigon after curfew when he crosses paths with US Army clerk Tommy Banks and his girlfriend, Grace Waverly. Grace says she's a peace tourist, but she's also a member of RAW-an anti-war group bent on stopping the war by any means necessary.

When Grace turns up dead in the Saigon River, Ben gradually uncovers a much larger conspiracy that involves an opium-pushing arms dealer and spies of every stripe. Rich with authentic details, this gripping thriller will immerse you in the tumultuous atmosphere of the 1960s as two very different men pursue justice, love, and survival in a world torn apart by war.
