Leonard and Sheldon are brilliant physicists, the kind of "beautiful minds" that understand how the universe works. But none of that genius helps them interact with people, especially women.

Season Six kicks off in space, where Howard is caught in an argument between his wife and his mother over the topic of where he'll live when he gets back. Back on Earth, Sheldon decides to hire Alex, a young female assistant which makes Amy feel threatened.

Meanwhile, Penny confesses that something is wrong with her relationship with Leonard to the girls, and Raj bonds with Stuart the only guy more lonely then he is. Find out what surprises are in store for everyone in all 24 episodes from season 6.
