Comedy set in 1977, in which a renowned playwright (Alberto San Juan) tries to shoot a social protest drama starring a doldrums folk, former child star (Natalie Poza) and produced by a producer and shameless liar (Miguel Rellán). Inexperience, ambition, lack of means and the love-hate relationship with the star director shooting become a craze.

Juan and Sonia arrive at a large old house, an ideal place to raise their newborn son. When, one night before going to bed, they check the operation of the monitoring device installed in the baby's room, they discover that someone is sitting next to the crib.
