Ver Cuevana 3. Night has just fallen. It's time to sleep, except for Sandier, whose hard work is just beginning. On his bike, with a large canvas bag filled with sand on the back, he crosses the city to put the children to sleep. Standing in front of a house, ready to enter, he discovers that he has clumsily forgotten his bag on his bike. He turns around and is stunned to find that his bike has disappeared.
