When a group of dysfunctional and unpublished writers unexpectedly welcomes young Hannah (Kaley Cuoco), they could never have anticipated her swift rise to fame. Hannah, who has only taken a few writing classes and has barely read a novel, somehow finds herself at the center of their aspirations, despite her complete lack of experience in the literary world.
One of the group members, Colette Mooney (Teri Polo), struggles against a flood of rejection letters from agents and publishers. Her husband, Alan (Dylan Walsh), endlessly records half-baked ideas but fails to put any of them into practice, seeing himself as the group's leader. Meanwhile, Henry Obert (Chris Klein) grapples with writer's block while harboring a significant crush on Hannah; he juggles his time between delivering pizzas and cleaning carpets while desperately trying to complete a third novel.
John K. Butzin (Dennis Farina), an aspiring writer with dreams of emulating Tom Clancy, resorts to self-publishing with the support of Sigrid (Tricia Helfer), a hardware store employee who believes in his potential. William Bruce (Jonathan Bennett), who fancies himself a ladies' man and a devoted fan of Charles Bukowski, is convinced he stands out as the only true writer in the group.
Despite her inexperience, Hannah manages to snag a literary agent and secures a lucrative deal to adapt her first manuscript into a Hollywood film. However, the camaraderie within the Authors Anonymous group swiftly transforms into jealousy and resentment. Struggling with desperation, John pays a dubious publisher $250 to print his novel, only to find the cover marred by a misleading image.
Opportunity knocks when an agent, David Kelleher (Jonathan Banks), visits Alan's optometrist shop, prompting Alan to introduce Colette. She presents David with her manuscript, which he dismissively tosses aside as he exits.
As tensions rise, Hannah realizes that nurturing her relationships within the group proves nearly impossible. Nevertheless, she tries to support Henry in reigniting his writing career. As their bond deepens, Henry educates Hannah about his favorite novels and even shares a gentle kiss with her, although Hannah makes it clear she prefers to keep things casual.
The group's dynamics shift dramatically when John announces that Hannah has landed a stunning six-figure deal for her screenplay, plunging everyone into a state of sadness and frustration. William's desperation leads him to ask Colette for a significant sum, while Alan discovers their plan and confronts Colette in anger. In contrast, John attempts to rejuvenate his career with a book signing event at Sigrid's store, but it flops.
Alan eventually kicks William out of the group after a heated exchange, during which William claims Henry possesses the most talent but remains hopelessly enamored with Hannah. The discontent peaks at a signing for Richard Broadwell, Henry's literary idol, who, instead of engaging with the group, unexpectedly asks Hannah out, further inciting their jealousy and suspicion that her success hinges on flirtation.
In a twist of kindness, Sigrid covertly buys John's books to uplift his spirits. However, Colette aggressively pursues agents and lands a co-author deal when one agent recognizes her spiritual guru, resulting in a lucrative book deal for them both. Meanwhile, Henry discovers that Hannah is involved with Richard, deepening his grief.
The group reaches a breaking point when Hannah reveals her departure to join Richard as his mentee. Following her exit, John opts to leave, and Alan's marriage to Colette crumbles. Several months later, at Hannah's book signing event, Henry finds her still involved with Richard.
In a humorous closing, David narrates a chance encounter with Henry while ordering pizza, leading to an accidental bond over a discount on carpet cleaning services, culminating in David becoming captivated by Henry's novel and ultimately agreeing to represent him.
