Georgina Salt, portrayed by Heather Graham, is a young contractor residing in London, yearning for the fulfillment of motherhood, which she believes is the missing piece in her life. The film opens with her long-term boyfriend, Zak (Tom Ellis), on a phone call with his sister who has just welcomed a baby girl. It's clear that Georgina is more captivated by the newborn than Zak's conversation. After the call, the couple transitions to their bedroom, where Georgina attempts to seduce Zak. However, Zak's use of a condom leaves Georgina feeling disappointed.
The following day, while shopping for a gift for Zak's sister's baby with her mother, Vivienne (Vivienne Moore), Georgina finds herself overwhelmed by the joy surrounding baby items, which deepens her sadness. A doctors' advertisement for women seeking pregnancy prompts her mother to mention Georgina's aunt, leading to a surprising revelation: Georgina's aunt, whom she assumed was a lesbian for not having children, struggled with infertility. This distresses Georgina, prompting her to spend £150 on a baby blanket before exiting the store.
At Zak's sister's home, Georgina is finally allowed to hold the baby, which brings her immense joy, while Zak clowns around with a belly sculpture. However, after accidentally breaking it, Zak shifts the blame onto his sister's young son, leading to a tense car ride home. Frustrated with Zak over the statue fiasco, Georgina is about to pose a question when Zak interrupts, asserting, "I do not hate babies." Misinterpreting his comment as an admission of disdain for children, Georgina insists that Zak pull over, leading him to crash at a friend's place while she returns home in anger.
Earlier, Georgina visits the clinic with her best friend, Clem (Mia Kirshner), to check on her egg count. Upon receiving a call from the doctor, they learn that Georgina has only one egg left, and she’ll be ovulating for the next four days. The two women develop a plan to help Georgina find a partner, starting with a 'date' with Justin (Orlando Seale). Georgina's bold declaration about her single egg surprises him, setting the stage for their unconventional pursuit.
Georgina attempts to host an 'open house' to attract prospective partners, though she initially turns away several unsuitable candidates. Eventually, an appealing man arrives, but just as things heat up, Zak's call interjects, prompting Georgina to send him away. Meanwhile, Zak is entangled with Alexandra (Ruta Gedmintas), whose presence complicates Georgina’s frustrations.
Day after day presents new challenges as Georgina tries different strategies to meet someone. A visit to a funeral leads to embarrassment when her planning notes are discovered by a man she tries to seduce, further complicating her efforts. In a nightclub setting, Georgina tries to enhance her allure but ends up humiliated when a charming stranger absconds with her money.
Meanwhile, while Zak makes his way back to London, Georgina begins considering artificial insemination, despite her heartfelt hope to be with Zak. A hilarious mishap occurs when she accidentally squirts the sperm on a birthday cake, and her friend Clem suggests they ask Justin to help her conceive, though his reluctance creates tension. As events unfold, misunderstandings with Zak put a strain on Georgina's pursuit of motherhood.
Amidst all this chaos, a pivotal moment arises when Zak ultimately confronts Georgina about their feelings. In the end, after several months filled with comedic yet poignant struggles, Georgina's journey culminates in joy when she discovers that she is pregnant. The film closes at a birthday celebration for Zak, where they share not only their engagement but also the wonderful news of her pregnancy, bringing the story full circle with hope and love.
