Two people, on opposite sides of a gateway find themselves in a rather life-threatening situation. Louder and louder the monster pounded on the door as Feliciano looked for a way out, at the same time a confused nine-year-old stared at the strange painting (like the others are not), hoping it is a gateway out. But instead, of an exit it became an entrance for another.
