Lily Valance is determined to forget the horrors of the war by throwing herself into the decadent pleasures of the 1920s and pursuing her career as a music hall singer. When she meets Captain Stephen Winters, a decorated veteran, she's immediately drawn to his wealth and status. And Stephen, burdened by his guilt over surviving the Flanders battlefields where so many soldiers perished, sees the possibility of forgetting his anguish in Lily, but his family does not approve. Lily marries Stephen, only to discover that his family's facade of respectability conceals a terrifying combination of repression, jealousy, and violence. When Stephen's terrors merge dangerously close with reality, the truth of what took place in the mud and darkness brings him and all who love him to a terrible reckoning.
