Liv is an eleven year-old Olso girl who begins to notice strange events unfolding on the ground level of her apartment building. When Liv and her best friend Thomas venture downstairs to get to the bottom of the mystery, they discover an aged photograph of two girls and a cat. Suddenly, the cat comes bounding out of the photograph, prompting young Liv to fall unconscious. She starts experiencing vivid visions. Could it be that someone is trying to tell Liv something, and are these events tied to a strange catastrophe that unfolded on these same grounds nearly one hundred years ago? Despite the fact that few adults seem to believe her incredible story, an elderly neighbor living upstairs may just have the information that will allow Liv and Thomas to unlock the truth behind the strange events unfolding all around them.
