Helen (Louise Brealy) finds herself in a small, sparsely furnished room, her few belongings hidden away. The appearance of a young man reveals him to be "Gary" (Celyn Jones), her husband, who has relegated her to the spare room to accommodate his new girlfriend, "Amy" (Emily Fairn), and their baby. Understandably upset by this situation, she tolerates it because she wants to remain nearby for his mother, "Gwen" (Sorcha Cusack), who is seriously ill. The few bright spots in Helen’s life come from her job. She works alongside a close-knit group of women whose task involves packing chickens. To break up the monotony, they invent silly games and try to lift each other's spirits, particularly during night shifts. Then "Joanne" (Annabel Scholey) enters the picture. Despite an awkward initial meeting, it’s clear that these two share a complicated past, and the film gradually reveals more about their histories alongside some genuinely funny moments. Much of the humor comes from "Paula" (Beverly Rudd), who is rough around the edges but ultimately kind-hearted and delivers many of the script's best lines. While the storyline is fairly straightforward, director Janis Pugh introduces unexpected twists to maintain audience engagement, and there are occasional musical interludes that use the film’s soundtrack—often to underscore Helen’s unhappiness. The acting is strong across the board, with a good supporting cast, touches of social observation, and an odd connection between the women and one of those mannequin heads once used for practicing makeup application. It might also be considered a cautionary tale regarding chicken consumption; the processes these women undertake while plucking the birds could easily deter anyone from eating them again.
