The year is 2029. The world has become intensively information oriented and humans are well-connected to the network.

Three time periods - young adolescence, mid-teen and young adult - in the life of black-American Chiron is presented. When a child, Chiron lives with his single, crack addict mother Paula in a crime ridden neighborhood in Miami. Chiron is a shy, withdrawn child largely due to his small size and being neglected by his mother, who is more concerned about getting her fixes and satisfying her carnal needs than taking care of him. Because of these issues, Chiron is bullied, the slurs hurled at him which he doesn't understand beyond knowing that they are meant to be hurtful. Besides his same aged Cuban-American friend Kevin, Chiron is given what little guidance he has in life from a neighborhood drug dealer named Juan, who can see that he is neglected, and Juan's caring girlfriend Teresa, whose home acts as a sanctuary away from the bullies and away from Paula's abuse. With this childhood as a foundation, Chiron may have a predetermined path in life, one that will only be magnified in terms.

Sad story of a waif, Gelsomina, who is sold by her mother to Zampano for 10,000 lire and a few kilos of food.

He performs in village squares and then passes the hat for whatever the normally small crowd is prepared to give. He teaches Gelsomina a drum roll as part of his introduction. He doesn't treat her well and when she tries to run away, he beats her. They eventually join a small traveling circus where they meet a tight-rope walker who convinces Gelsomina to question her choices.
Two parallel stories are told. In the first, a group of research scientists from a variety of backgrounds are investigating the strange appearance of items in remote locations, primarily desert regions. In continuing their investigation, one of the lead scientists, a Frenchman named Claude Lacombe, incorporates the Kodály method of music education as a means of communication in their work. The response, in turn, at first baffles the researchers, until American cartographer David Laughlin deciphers the meaning of the response. In the second, electric company lineman and family man Roy Neary and single mother Jillian Guiler are among some individuals in Muncie, Indiana who experience some paranormal activity before some flashes of bright lights in the sky, which they believe to be a UFO. Roy becomes obsessed with what he saw, unlike some others, especially in some form of authority, who refuse to acknowledge their belief that it was a UFO in not wanting to appear crazy. That obsession.
