Hannah Horvath (Lena Dunham) and her girlfriends continue to hunt for success--creatively, professionally, and romantically--in New York City and beyond in Season 4 of the hit HBO comedy series. This season, Hannah leaves New York to attend the prestigious Iowa Writers' Workshop, while confronting uncertainty in her relationship with Adam (Adam Driver). Meanwhile, Marnie (Allison Williams) pursues a music career while balancing her professional and romantic relationship with Desi (Ebon Moss-Bachrach); Shoshanna (Zosia Mamet) graduates and begins interviewing for jobs while sorting out her relationship with Ray (Alex Karpovsky); and Jessa (Jemima Kirke) is trying out sobriety through AA, though her ability to stir up drama remains undiminished.
