High in the hills of Valencia, a forgotten house guards its secrets - untouched since Franco's forces tore through Spain in 1936. Emma Temple is the first to unlock its doors in 70 years. Emma makes it her mission to restore the place to its former glory. But for her aging grandmother, a British nurse who stayed in Valencia during Spain's devastating civil war, Emma's new home evokes memories of a terrible secret, a part of her family's past that until now has managed to stay hidden.
