Hamburg, Germany, 1939. Getting a passage aboard the passenger liner St. Louis seems to be the last hope of salvation for more than nine hundred German Jews who, desperate to escape the atrocious persecution to which they are subjected by the Nazi regime, intend to emigrate to Cuba.

The young film student Maria do Mar is working on a documentary about the old manor houses along the Douro River. It is the final project in her thesis on “Reality in Cinema”. Maria has an unlimited confidence in what is visible. Her candour and her naivety allow her to see the bright side of life – such as the beauty of the landscape and the authenticity of the place, or what’s left of it. But when Maria enters the final manor house on her list, she soon realises that something is going on in this house that is not as innocent as it first seemed. The manor is truly a house of horrors.
