Elio is a lonely 11-year-old boy struggling to rediscover joy in life after the tragic loss of his parents.He's also a boy who is infatuated with all things astronomy -- planets and galaxies and especially the potential of alien life. "Is life really out there?" he asks his Aunt Olga, a young woman who has been tasked with raising him but has found the role far more difficult than expected.He argues. He pushes her emotional buttons. It's so exhausting that she's reading the book Parenting Your Spirited Child -- but, so far, has found little to help."This just isn't how I thought my life would be," she confides to a friend.Olga is a talented major at a military base charged with tracking space debris, ensuring it doesn't collide with satellites or pose threats to people. Her interests aren't that different from his, and yet, they rarely connect.Their tension comes to a head one day when Elio tells her that he wants to live on a different planet with aliens who actually care about him. As he puts it: "One of them's gotta want me, because obviously you don't.""Of course I do -- we're family," she responds."You're not my family!" he fires back.Eventually, though, Elio gets his wish. His adventure begins when the military base receives a strange signal from outer space that is brushed off as background noise by military officials but taken seriously by an eavesdropping Elio, who sneaks into a top-secret room and sends Earth's official response. Before long, Elio is beamed up off a beach by a spaceship filled with a wild assortment of friendly aliens who want him to join their group. This group of aliens is known as the "Communiverse," where the greatest minds within advanced lifeforms of the universe gather to share knowledge and innovation.But not all is peaceful. That's because one specific alien — a violent, robotic-like alien known as Lord Grigon — is threatening to disrupt this peaceful alliance. He wants members of the Communiverse to admit him into their council — and then take over the galaxy.And when the members of the Communiverse reject his demand, Grigon threatens to return with a fleet of warships and destroy this interstellar alliance.Soon, Elio volunteers to arbitrate this intergalactic conflict. Will he survive?It's all part of the new Pixar movie Elio (PG).Here are three things parents should know about the film:Warning: Spoilers ahead!Photo Credit: ©Pixar
