Set against the backdrop of a small Indian town- Jamshedpur, Trio introduces us to the lives of Genia aka GE, Bonnie aka BO, and Sonnie aka SO - three school girls raised in an orphanage bound by their shared curiosity and unbreakable bond. Their ordinary lives take a dramatic turn when they stumble upon a mysterious artifact that reveals the existence of extraterrestrial life. They face head-to-head against a powerful alien EKA from the planet Z (about 8000 Light years away from Earth). EKA belongs to a lineage of aliens which are 1 million years ahead of us humans in evolution. They are way superior to us in all aspects of our lives. How will the TRIO take on the alien onslaught? Who will help them? Will mankind survive?
