The fourth season of The Big Bang Theory finds Leonard (Johnny Galecki) falling for Raj's sister Priya following his break-up with Penny (Kaley Cuoco). Meanwhile, Sheldon (Simon Helberg) finds romance with a neurologist who quickly establishes herself as Penny's new best friend. As Howard and Bernadette's relationship blossoms, Bernadette finds herself plagued by Bollywood daydreams starring Raj (Kunal Nayyar).

Two brilliant young physicists learn that the complex structures of atoms aren't nearly as perplexing as the inner-workings of modern women in this release featuring all 17 episodes of the The Big Bang Theory: Season One. The first season introduces viewers to the main characters: Leonard Hofstadter (Johnny Galecki), a brilliant but awkward experimental physicist; Sheldon Cooper (Jim Parsons), an even more brilliant theoretical physicist who lacks any kind of social niceties or understanding of sarcasm and irony; and Penny (Kaley Cuoco),a young blonde aspiring actress who immediately catches Leonard's attention. Rounding out the group are Howard Wolowitz (Simon Helberg), an aerospace engineer who still lives with his mother; and Rajesh Koothrappali (Kunal Nayyar), an astrophysicist who's so shy around women that he's unable to speak to them without the aid of alcohol.
