Upon hearing of her mother's death, jaded teenage loner Purslane Hominy Will returns to New Orleans for the first time in years, ready to reclaim her childhood home. Expecting to find her late mother's house abandoned, Pursy is shocked to discover that it is inhabited by two of her mother's friends: Bobby Long, a former literature professor, and his young protege, Lawson Pines. These broken men, whose lives took a wrong turn years before, have been firmly rooted in the dilapidated house for years, encouraged only by Lawson's faltering ambitions to write a novel about Bobby Long's life. Having no intention of leaving, Pursy, Bobby Long and Lawson are all forced to live together. Yet as time passes, their tenuous, makeshift arrangement unearths a series of buried personal secrets that challenges their bonds and reveals just how inextricably their lives are intertwined.
