Celeste García, a 60-year-old former schoolteacher and current guide at the Havana Planetarium, is looking for a life change. When a group of aliens land in Cuba offering earthlings a chance to visit their planet, Celeste signs up for the journey hoping for a better and more fulfilling life.

This drama features three stories about the bonds between children and absent parents. A Cuban boy who lives in poverty with his mother longs to visit his father in the United States, a Moroccan girl attempts to reunite with her father, and in Mexico, and a boy disobeys his father to visit a strange lagoon. These related vignettes showcase the powerful hold that parents have upon their children, which often remains strong despite their absence.
