The recollections of a Portuguese teacher in the present will make us follow his father, Manuel, former fighter in our colonial war and constantly tormented with those memories. He'll walk us through the depths of the physical sites that haunt him - from training barracks to the lakes and gardens of his youth and infatuation - and also to his memory's gulf - war and passion combined, entangled, in a battle that questions or howls immemorial existential doubts.
