The early life of child genius Sheldon Cooper, later seen in The Big Bang Theory.

A hedonistic jingle writer’s free-wheeling life comes to an abrupt halt when his brother and 10-year-old nephew move into his beach-front house.

The Big Bang Theory is centered on five characters living in Pasadena, California: roommates Leonard Hofstadter and Sheldon Cooper; Penny, a waitress and aspiring actress who lives across the hall; and Leonard and Sheldon’s equally geeky and socially awkward friends and co-workers, mechanical engineer Howard Wolowitz and astrophysicist Raj Koothrappali. The geekiness and intellect of the four guys is contrasted for comic effect with Penny’s social skills and common sense.
