The assorted humiliations, disasters and rare triumphs of four very different twenty-something girls: Hannah, an aspiring writer; Marnie, an art gallery assistant and cousins Jessa and Shoshanna.
Hannah is enjoying new success as she lands a plum writing assignment that could dramatically change the course of her life. Meanwhile, Marnie, now in a relationship with Ray, seeks to maintain her post-divorce independence; Jessa and Adam, now also a couple, embark on a creative project together; and Shoshanna lands on her feet at a marketing agency.
