Maria, a 7-year-old girl, is watching her favourite programme. She dances and sings like crazy while watching TV. Her mother, who can't stand her any longer, tells her that she has to go out for a moment to buy something for dinner, but Maria only pays attention to her programme, although she asks her mother to bring her some plums. Time flies by and by the time Maria realises that several hours have passed, it is night and she is alone at home... until someone who seems to be her mother rings the doorbell. She has lost her keys and needs her little girl to open the door. Maria will have to decide whether the woman on the other side is really her mother bringing the things to cook dinner or whether it is someone who also wants to cook dinner... but with her.
