Year 1940. A town lost in the Castilian plateau. It’s Sunday and the Cinema van arrives. In a mixed-use dilapidated building, the projection of the movie “Doctor Frankenstein” is improvised. For ninety minutes through the lonely streets of the town the old words of the romantic myth echo. In the improvised room, among the spectators, were two sisters, eight and six years old. Their names are Isabel (Isabel Tellería) and Ana (Ana Torrent). They carefully follow the projection. The little girl, Ana, asks the oldest why the monster kills and why he finally dies. They are the first questions that Isabel solves thanks to her imagination: the monster is a spirit that can appear as her friend and summons it through certain words. What for Isabel is a game of imagination, for Ana ends up being a vital reality. She loves the monster. She looks for him. She summons him. The old house where the girls live with their parents is filled with the presence of something impalpable that only Ana seems deeply determined to discover. Fernando (Fernando Fernán Gómez) and Teresa (Teresa Gimpera), the parents, live their nostalgia, their frustrations, without taking advantage of what their little daughter’s mind hides. One day, Ana disappears. The search will be harrowing. The girl will be found. But no one, except her, will be able to know the end of the adventure.
