Lorelai Gilmore has two twin daughters. One goes to Chilton, Rory obviously, but the other one goes to a fancy school for the arts in New York, Iris is her name. Her mom couldn't think of any other name after naming Rory after herself, so she named her other daughter after the unique flower, just like how Lorelai is named. So what happens when Iris is back in town after some trouble at her school and is now being sent to Chilton with Rory, and she inevitably runs into the new in town bad boy, Jess Mariano.
