Leonard and Sheldon are brilliant physicists, but none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty, Penny, moves in next door. Sheldon is content spending his nights playing Klingon Boggle with their socially dysfunctional friends. However, Leonard sees in Penny a whole new universe of possibilities ... including love.
