As Sid worries about the situation in Germany, Louise discovers an enemy within her own family.

The Light Years tells the story of the extended Cazalet family.

Set in the lead up to the outbreak of the Second World War, it appears that the Cazalets have it all.

But we soon discover that infidelity, indiscretions, jealousies and misplaced loyalties lurk just beneath the surface.
