Set in postwar Germany in 1946, Rachael Morgan (Keira Knightley) arrives in the ruins of Hamburg in the bitter winter, to be reunited with her husband Lewis (Jason Clarke), a British colonel charged with rebuilding the shattered city.

But as they set off for their new home, Rachael is stunned to discover that Lewis has made an unexpected decision: They will be sharing the grand house with its previous owners, a German widower (Alexander Skarsgård) and his troubled daughter. In this charged atmosphere, enmity and grief give way to passion and betrayal.
