Plot Synopsis

Executive produced and narrated by Jim Parsons, YOUNG SHELDON is a half-hour comedy series that centers on THE BIG BANG THEORY's Sheldon Cooper -- specifically his life as a child, when he was a once-in-a-generation nine-year-old capable of advanced mathematics and science, but who learned that it wasn't always helpful growing up in East Texas, a land where church and football are king. 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 in a town where he just doesn't fit in. Sheldon's older brother, Georgie, does the best he can in high school, but it's tough to be cool when you're in the same classes with your odd 9-year-old brother. Sheldon's twin sister, Missy, sometimes resents all the attention Sheldon gets, but she also remains the one person who can reliably tell Sheldon the truth. Finally, there's Sheldon's beloved Meemaw, his foul-mouthed, hard-drinking Texas grandmother who is very supportive of her grandson and his unique gifts.
