A knock on your door sets in motion the feeling of anxiety. Should you open? Who, or what, will you encounter if you do? The characters of this continuous-shot anthology film – a billionaire, a commercial pilot, a trainee police officer, and a young single mother – find themselves in critical situations, facing the unknown. To make the right choice they must look deep within themselves, and recognize the true source of their fears.
