All of Us Strangers

In the organizer's words:

One night in his almost empty London tower block, Adam has a chance encounter with his mysterious neighbor Harry that disrupts his everyday rhythm. They quickly become close and the otherwise introverted Adam quickly confides in the empathetic Harry. He tells him about his childhood and his plans for a book he wants to write about his life. To do so, he embarks on a difficult journey into the past. He travels to his childhood home, where everything seems to be just as he left it. Even his long-dead parents don't seem to have aged a day. Has his long period of loneliness and grief caused him to lose control of reality? After all, how else would it be possible to suddenly come face to face with his deceased parents?
