2 BROKE GIRLS is a comedy about the unlikely friendship that develops between two very different young women who meet waitressing at a diner in trendy Williamsburg, Brooklyn, and form a bond over their dream of one day owning their own successful cupcake business.  Only one thing stands in their way – they're broke.  Sarcastic, street-smart Max Black met the sophisticated, school-smart Caroline Channing when the uptown trust fund princess was having a run of bad luck due to her father's Wall Street scandal, which caused her to lose all her money and forced her to give waitressing a shot.  At first, Max sees Caroline as an entitled rich girl, but she's surprised to find that Caroline has as much substance as she does style. When Caroline discovers Max's knack for baking amazing cupcakes, she visualizes a lucrative future for them and they begin to save money to reach their start-up money goal of $250,000.  As the girls' cupcake tally expands week-to-week, they become closer to their goal and to each other.  At the diner they are surrounded by their offbeat, colorful "work family": Oleg, an overly flirtatious cook; Earl, a hip 75-year-old cashier; Han, the eager-to-please owner of the diner; and Sophie, the girls' outrageous upstairs neighbor. As Max and Caroline climb toward their goal, we see that their "smarts" plus their "hearts" might just be the recipe for success.
