Urzelina is a half-hearted level crossing attendant. In the middle of the day, she drinks a cup of half milk, half coffee and eats half a piece of toast. Her days are also spent halfway between the past and the present, working on the railway line. One day, something different happens in her routine, forcing her to perform a task. It is this change that unlocks her movements, even though they are no longer necessary. Urzelina is trapped in what she no longer has.
