In the seemingly perfect suburban landscape of New York, Laney Brooks finds her fragile existence shaken as she retreats from the chaos of her life into the solitude of the bathroom. In this private escape, she reflects on the tension-filled argument with her husband, Bruce, regarding their new pet, a dispute that seems trivial in the grand scheme of her growing unease. As the morning light seeps into their home, Laney grapples with her inner turmoil, triggered further by her son Eli's nighttime fears that awaken her protective instincts as she tries to soothe him.
With Bruce occupied and unaware of the unfolding chaos, Laney's attention drifts to the medicine cabinet as she prepares lunch for their children, a mundane responsibility overshadowed by her increasing frustrations. The morning commute is lined with challenges: a relentless traffic guard, the school administration's stringent security requirements, and the reluctant separation from her kids, fueling her simmering agitation, which she briefly alleviates by lighting a cigarette.
Seeking an escape from her discontent, Laney turns to Donny, Susan's husband, igniting a whirlwind of passionate yet disdainful encounters. Her subsequent shower and the audacious theft from Donny's wallet reflect her deep longing to break free from her struggles. That evening, her drinking spirals out of control as tensions rise around the dinner table when Eli voices his friends' critical opinions, leading to volatile decisions marked by harsh words during a tense phone call, a reckless binge of pills and cocaine, and an intense urge for self-pleasure.
Just as Laney hits rock bottom, Bruce steps in, whisking her away to a rehabilitation center where she initially resists the help offered. Faced with physical distress in the facility's restroom, she confronts the profound issues stemming from her father's abandonment, a revelation that darkens her psyche.
As Laney traverses the rehabilitative process, she is confronted with the devastating consequences of her addiction on her loved ones, particularly Eli and Janey. Family visits to the facility heighten her anxiety when she notices Eli's emerging tic, a painful reminder of the fallout from her actions. Despite her attempts at reconciliation, Bruce remains emotionally distant, amplifying Laney's sense of isolation and desperation. Seeking solace, she confides in Dr. Page (character A), expressing her wish to rediscover joy and hope in life. The physician's advice rings clear: take your medication, believe in yourself, and strive for redemption.
When Laney returns home post-rehab, a semblance of normalcy envelops the family as they gather for a celebratory gathering, adorned with cake and laughter, despite a blackout that only enhances their warmth. However, underlying anxieties emerge during a counseling session concerning Eli's fears about rehab, hinting at deeper issues yet to be resolved.
Later, as they celebrate Susan's pregnancy at Donny's restaurant, Laney's chaotic nature shines through when she insults another couple, escalating tensions. This culminates in a seminar trip to a hotel near Roger's house, which unexpectedly sets the stage for her first meeting with her half-sister, Daisy. Digging into her family's past leads to shocking revelations about her grandmother's death, pushing Laney to confront Roger's dismissive explanations, further unraveling her sense of stability.
Staggering back to the hotel alone after Bruce's check-out, Laney finds herself spiraling further into despair, drowning her sorrows in alcohol as Bruce prepares for the worst. Their violent confrontation forces Laney into isolation once more, with the children staying with Bruce's sister while she faces her demons alone. A fleeting moment of respite occurs during Eli's piano recital, but the applause fades as she retreats to the bathroom, desperately trying to escape through drugs.
An ill-fated attempt to snort cocaine leads to a series of escalating crises, culminating in a reckless drive through traffic, eyes closed, as she seeks to escape the pressures of her life. Surprisingly unscathed, Laney shows up at Donny's seeking help—only to be met with rejection, leaving her even more adrift. In her desperation, she resorts to anti-anxiety pills, leading her down a treacherous path of recklessness.
Laney's descent continues as she succumbs to a dangerous night out that ends with her battered and bloodied, ultimately stumbling home only to face Bruce's harsh judgment from the shadows of their home. With her mask of normalcy shattered, she steps into the early dawn, burdened by the weight of her choices, signaling a poignant and turbulent journey yet to unfold.
