Turbulence (2000)

I'm not entering anywhere, but I'm leaving everywhere

After a restless night he is awoken by his doorbell insistently ringing. Through the peephole, he sees a stranger. He doesn't know why that man is there but is immediately certain of one thing: he represents a terrible threat. He quickly dresses and manages to sneak away, no doubt in his mind that the stranger is pursuing him, and that the nightmare has only just begun.
