Leonard and Sheldon are brilliant physicists - wizards in the laboratory, but socially inept outside of it. Enter beautiful, free-spirited neighbor, Penny, who aims to teach them a thing or two about life.

While Leonard spends his days looking for love, Sheldon is quite content video-chatting with platonic partner Amy Farrah Fowler, or playing Star Trek 3D Chess with their ever-expanding universe of friends, including fellow scientists Koothrappali and Wolowitz, and Wolowitz' new wife, the adorable microbiologist Bernadette.
