The cinematic journey unfolds through the intricate life of Pippa Lee (Rooney Mara), whose experiences are deeply explored through a series of flashbacks and moments of personal reflection. Growing up as the youngest child and only daughter in a large Christian family, Pippa finds herself under the constant scrutiny of her mother, Suky (a captivating performance), who is obsessively fixated on her own physical appearance.
As Pippa navigates the rocky waters of her teenage years, she uncovers a disturbing truth about her mother: Suky's reliance on amphetamines to manage her erratic mood swings. This revelation triggers a confrontation that propels Pippa towards a journey of self-exploration. In her quest for independence, she moves in with her aunt Trish (who delivers a scene-stealing performance) and her girlfriend Kat, both of whom are part of an unconventional living arrangement.
Trish's eventual discovery of Pippa's involvement in risqué photo shoots with Kat and their circle of friends results in her banishment, forcing Pippa into a whirlwind lifestyle characterized by experimentation with drugs and performing exotic dances. It is in this tumultuous setting that she meets the charming yet troubled Herbert "Herb" Lee (a beautifully nuanced portrayal), a publisher who is thirty years older than her.
As Pippa and Herb's love story unfolds—despite his existing marriage—they embark on a weekend getaway with friends who share their free-spirited outlook. However, their seemingly perfect retreat is abruptly derailed when Herb's wife tragically takes her own life during lunch, which compels the couple to confront the challenging waters of divorce and remarriage.
Eventually, Pippa and Herb tie the knot, welcome two children, and settle into a comfortable life. Yet, as time passes, Pippa finds herself increasingly distanced from her own dreams and ambitions. Herb's infidelities and their emotional rift catalyze Pippa's urge to reassess her life choices, leading her to reconnect with Chris, who is significantly younger.
After Herbert Lee passes away from cardiac arrest, Pippa sheds the constraints of her "perfect wife" image, entrusting the arrangements for his memorial and legacy to their children. As she steps into a new phase of her life, Pippa drives off into the sunset with Chris, symbolizing her liberation and the reclamation of her identity.
