Anna is a woman training to be a long-distance runner. She finds herself on the outskirts of the city. All access beyond this point is strictly prohibited. Anna, like her fellow citizens, is bound by law to declare her exact location to the authorities by calling the official center. She just needs to make this one last call and provide her daily report, before she can proceed with her plan: escape. But when the well-trained phone operator across the other end of the line suspects her moves, Anna will realise that the clock is ticking against her. There is no turning back and the time is now to either run away for good, or die trying.
