The nerdy origins: A show born of science and sarcasm

The show is set in Pasadena, California. It revolves around socially awkward geniuses Leonard Hofstadter and Sheldon Cooper. They are both physicists at Caltech. Their journey involves attempts to make sense of everyday life. They also explore dating and pop culture.
