Mainland student Yi Yao comes to study in this busy city. Before her roommate arrives, she is all alone staying in a rented apartment of an old tenement building. Unfamiliar with everything, she tries hard to explore around only finding that the neighbours are noisy, weird and unhelpful; especially after the man living opposite to her getting killed. Being hungry and helpless, she locks up herself in the flat and acts strangely. Can anyone help her? Through a series of mysteries, social issues like Mainland students flocking to Hong Kong, overcrowding living area and indifferent neighbours are covered in the short film.
