Girlfight is a fierce rites of passage story about a quick-tempered young woman, Diana Guzman (Michelle Rodriguez) who lives in the Brooklyn projects with her dismissive father Sandro (Paul Calderon) and younger brother Tiny (Ray Santiago). Diana witnesses generations of families who never move beyond the confines of their small world. She has nothing to lose - or gain - by not controlling her violent temper. For Diana, it's hit or be hit, and she'd much rather be the one packing the punch. Diana finds discipline, self-respect and love in the most unlikely place - a boxing ring.
