If you’ve ever wondered who the alpha males are among the Caltech collective, you’ll find out in this exploration of the group dynamic. After a rift opens up, Raj and Leonard do some lateral thinking for a project about communicating with aliens. “Penny has about 20 different ways of rolling her eyes that each mean something different…” offers Leonard.
Look out for Penny knocking on a door in the manner of Sheldon and further examples of Bernie’s acid tongue. (Is she really the Alien in disguise?) There are two welcome breaks from the norm: one internal monologue and a very sci-fi ending. After eight series they can afford to go a little crazy.
Raj is asked to create a message on the off-chance a Nasa mission discovers alien life, and the guys fight over what he should do. Meanwhile, Penny contemplates returning to acting. Comedy, starring Johnny Galecki, Jim Parsons, Kaley Cuoco and Kunal Nayyar.
