Howard is determined to pick up women at a bar, with the help of a new fragrance he's concocted. Meanwhile, Raj is hit with a newfound ability to speak to women when he's drunk, leading to some unexpected encounters.

Sheldon, however, is resistant to the idea of romance and insists on sticking to his routine. However, that all changes when he meets a woman named Dr. Stephanie Barnett at work, who takes an interest in him. The two hit it off, but their differences quickly become apparent - Stephanie is a biologist and isn't quite as scientifically-minded as Sheldon. Despite this, the pair decides to give their relationship a chance.

Leonard, on the other hand, is caught in a love triangle between Penny and his new colleague, Dr. Leslie Winkle. Leslie is just as nerdy as he is, leading to some hilarious discussions about science and philosophy.
