Best friends Laura, a struggling writer working as a barista, and her best friend and flatmate Tyler, an American woman who is estranged from her family, are both heavy partiers living in Dublin. The early part of the film shows their close friendship in their late twenties as they consume large quantities of wine and drugs through the night, sometimes engaging in casual sex with a man but mostly just enjoying each other's company. Tyler is included in Laura's family gatherings, with a pregnant sister playing a part in the plot and character development. Circumstances change when Laura meets and then gets engaged to concert pianist Jim, who shortly afterwards gives up alcohol. Laura continues her partying lifestyle with Tyler, but starts spending nights with Jim. Inevitably the dynamics of the various relationships change, and more so after they become friends with a poet, Marty, to whom Laura is attracted, and his circle of literary friends. Laura struggles to make progress with her novel throughout the film. Various events in each of their lives unfold, with questions about life, and especially women's roles, raised and explored both implicitly and explicitly. With the development of the women's friendship front and centre of the film, it doesn't take the easy route to a typical neat and happily resolved "Hollywood ending", but ends optimistically with Laura finding her creativity beginning to flow as she finds a way forward.
Hyde said that it was the book which drew her in and inspired her to make the film, giving voice to women's experiences in a way that she hadn't seen very often on screen and in a way that felt connected to her own experience. She and Unsworth worked collaboratively from early in the creative process. The film was made in and around Dublin, whereas the book is set in Manchester. Shawkat said she was drawn to the film owing to its being driven by women, and she was able to bring her life experience into her creation of the character. Both main actors agreed that the personal chemistry between the two worked well on set because they had hit it off in real life.
Sundance said "Shawkat’s live-wire performance gives Tyler an anarchic comic edge that perfectly complements Grainger’s soulful turn as the conflicted and creatively blocked Laura". The Adelaide Review called it "a visually stunning and often surprising film". IndieWire’s Kate Erbland said that Grainger and Shawkat are wonderful together, and that the film "revels in the messiness of life, and the many love stories it can contain”. Variety’s Guy Lodge hailed the comedy as a commercial leap forward and wrote of its "ideally matched stars" and said that it compared favourably with the "more superficially subversive female leads of comedies like Trainwreck". The Hollywood Reporter’s Leslie Felperin found Unsworth’s script "insightful in its treatment of the complexity of female friendships". In the UK, The Guardian's Benjamin Lee called the film "one that attendees should be breathlessly, excitedly discussing around town, urging everyone else to see immediately", and Time Out said it "should delight anyone who watches it".
