Life is talking about silly stuff with the people you love.

Luna is a 6-year-old girl who doesn't want her mother to leave her with the babysitter every time she has to go to work. Her mother, Sara, is a flight attendant and has invented a game to help her daughter cope with her absences: bringing her stones from every place in the world she travels to. Each stone will be a new story to tell. Luna's imagination runs wild every time her mother leaves for distant countries, immersing herself in imaginary worlds unknown to her.

Not so long ago there were monumental movie theaters in the streets and avenues of Madrid, the capital of Spain, authentic cathedrals erected during the golden age of film exhibition, now converted into 3D dinosaurs, whose remains speak of the past and somehow anticipate the future.
