Judith Moore faces a troubling confrontation with her husband, Bob, during dinner when she brings up suspicions of his infidelity. Initially, Bob denies the claims, but after considerable pressure, he spills the truth: his affair is with a 34-year-old pediatrician. This shocking admission shatters Judith's illusions about their seemingly idyllic marriage. Devastated, she retreats to her apartment, where she encounters the building's isolated superintendent, Pat Francato, who also grapples with his loneliness following his wife's departure.
As Judith processes the pain of Bob's betrayal, she pours her energy into her work as a private caregiver for an elderly client. When asked about her own life, she reflects on her 16 years with Bob, recalling his steadfast refusal to have children. This realization—that their relationship was built on compromise and sacrifice—only deepens her sorrow.
Meanwhile, Pat's struggles with both loneliness and financial debt resonate with Judith, leading her to lend him money to settle his creditors. Their shared experiences foster a bond, and Pat's brother later provides him with the opportunity to show his gratitude, allowing them to enjoy a celebratory bottle of wine together.
At a local nightclub, Judith's heckling garners an unexpected rebuke from singer Liz Bailey, prompting Judith to reveal the tumultuous state of her marriage and a recent transient encounter.
After a late-night venture into erotic massages, Judith returns home intoxicated and withdrawn, brushing off Pat's tentative romantic overtures before he can express a desire for more than friendship. As insomnia plagues her, Pat stays by her side, ensuring she feels supported until fatigue finally overtakes her.
Their next outing leads them to the nightclub again, where Pat remains cheerful even as he senses Judith might not reciprocate his feelings. He introduces her to Liz and her boyfriend, whose effeminate nature provides a refreshing contrast to the conventional male bravado surrounding them.
Liz, embracing her role as a liberator, takes Judith on an exhilarating adventure to an exclusive after-hours women's dance club. Here, Judith is given a pill that liberates her inhibitions, leading her to lose herself in the music and return home at dawn. The following day, she faces an uncomfortable property sale with Bob, which is marred by heated arguments and pressure from his lawyer to forfeit her rights to their shared profits to avoid legal troubles.
In search of respite, Judith confides in Pat about her turbulent experience, and he proposes they unwind with dinner and perhaps a night out. During this outing, Pat surprises her by discussing plans for an Italian food import business, which holds potential for success. Although he offers her airline tickets to Italy as a generous gesture, Judith ultimately declines.
Months pass, and Judith finds renewed purpose working in the hospital's neonatal unit after successfully completing her nursing certification exam. One evening, she is drawn back to Liz’s club, where she delights in a passionate performance from Pat. Overwhelmed by a fleeting desire, she imagines kissing him, but is quickly reminded that he has found companionship with another woman.
With her heart heavy, Judith wanders the streets alone, each step echoing her acceptance of reality and the newfound sense of peace that now accompanies her journey.
