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 (series star IAIN ARMITAGE) deals with the world, his very normal family must find a way to deal with him. His father, George (series star LANCE BARBER), 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 (series star ZOE PERRY), fiercely protects and nurtures her son in a town where he just doesn't fit in. Sheldon's older brother, Georgie (series star MONTANA JORDAN), does the best he can in high school, but it's tough to be cool when your odd younger brother is already in college. Sheldon's twin sister, Missy (series star RAEGEN REVORD), sometimes resents all the attention Sheldon gets, but also remains the one person who can reliably tell Sheldon the truth. Finally, there's Sheldon's beloved Meemaw (series star ANNIE POTTS), his foul-mouthed, hard-drinking Texas grandmother who is very supportive of her grandson and his unique gifts. For 12 years on The Big Bang Theory, audiences have come to know the iconic, eccentric and extraordinary Sheldon Cooper. This single-camera, half-hour comedy gives us the chance to meet him in childhood, as he embarks on his innocent, awkward and hopeful journey toward the man he will become. JIM PARSONS narrates as adult Sheldon.
