For young Sheldon Cooper, it isn't easy growing up in East Texas. Being a once-in-a-generation mind capable of advanced mathematics and science isn't always helpful in a land where church and football are king. And while the vulnerable, gifted and somewhat naive Sheldon deals with the world, his very normal family must find a way to deal with him. His father, George, is struggling to find his way as a high school football coach and as father to a boy he doesn't understand. Sheldon's mother, Mary, fiercely protects and nurtures her son. For 12 years on "The Big Bang Theory," audiences came to know the iconic, eccentric and extraordinary Sheldon Cooper. In "Young Sheldon," audiences get a chance to meet him in childhood, as he embarks on his innocent, awkward and hopeful journey toward the man he will become. Jim Parsons, who plays the adult version of Sheldon on "The Big Bang Theory," narrates.
