As the chaotic decision to appoint Maria Hernandez as her guardian unfolds, Casey Brodsky finds herself at the center of a media storm that forces her parents, Albert and Lucy Brodsky, to confront the complexities of their own lives. This frenzy reveals the self-absorbed nature of this couple, whose private ambitions have long been cloaked in secrecy. The driving force behind this upheaval is Casey, who is wearied by the strife stemming from her parents’ troubled marriage.

Albert Brodsky’s journey takes a pivotal turn one fateful January night in 1973, when he scores a ride from Lucy van Patten, an aspiring children’s author caught in the web of her upcoming wedding to the gruff Navy man, “Bink.” As they navigate the scenic routes of Indiana, Lucy begins to shed her reservations, finding comfort in Albert’s engaging spirit. Eventually, they get married, united by a shared love for storytelling.

After relocating to California, Albert is presented with a chance to collaborate with a well-known Hollywood producer, tasked with reviving a script that had gathered dust. Lucy’s gifted writing skills become crucial in helping him overcome his creative stagnation, enabling them to co-create a cinematic gem that ultimately earns Academy Award acclaim for Best Director. However, behind this success, their marriage begins to fray.

As Albert dives deeper into his career, Lucy’s resentment grows stronger, feeling neglected and unrecognized for her influence on the screenplay. This unacknowledged partnership leads to her decision to divorce him, intensifying the challenges that Casey faces as Maria becomes her main caregiver during their tumultuous parenting situation.

It’s during this time that Albert becomes infatuated with Blake Chandler, a charming young woman he spots working at a hot dog stand. She lands a role in his next film, which achieves modest success, but their budding collaboration only serves to deepen the rift with Lucy. In a decisive move, she files for divorce, compelling Albert to reflect on the repercussions of his choices and the fragility of his once-happy marriage.

Following the separation, Albert guarantees that Lucy retains custody of Casey, while he retreats to a lavish Hollywood abode where Blake plays a significant role in his life. With this new arrangement, it’s evident that the most significant cost of the divorce is not merely their own happiness but also Casey’s emotional stability.

As Lucy’s suppressed frustrations boil over, she embraces the chance to pen a revealing tell-all novel, pouring her heart into the work and capturing her tumultuous journey. Meanwhile, Albert’s high standards lead him astray, culminating in the disastrous production of a musical adaptation of Gone with the Wind, titled Atlanta, which further isolates him in Hollywood, compounded by Blake’s demanding behavior on set.

In a surprising twist, Lucy’s book becomes an overnight success, propelling her to literary acclaim and allowing her to reclaim the luxurious mansion once owned by Albert. As she settles into her new reality, Lucy starts mirroring some qualities she had once criticized in Albert, gradually transforming into a persona evocative of a diva.

In a climactic showdown, Albert and Lucy’s clash over Casey’s custody culminates in an emotional tug-of-war, leaving their daughter devastated. This turmoil drives Casey to make the heart-wrenching decision to distance herself from both parents, seeking comfort with Maria and her family.

In court, Casey delivers a heartfelt testimony underscoring the significance of parental responsibility amid the fallout from her parents’ divorce. Witnessing the weight of their actions, both Albert and Lucy find themselves moved to tears. Ultimately, the court grants Maria legal custody over Casey, offering a semblance of resolution to this chaotic chapter.

Months roll by, and Albert slowly begins to restore his career, participating in lower-profile work, such as TV commercials and sitcoms, as a potential B-movie directing project lies ahead. Lucy, too, nurtures a return to her more grounded self. When fate brings both parents to Maria’s house for visitation, they decide to momentarily set aside their differences and share a meal at a family restaurant – a touching reminder that even amidst sadness, there remains a flicker of hope and healing.
