Helen (Louise Brealey) lives with her ex-husband, his 20-year-old girlfriend, their new baby, and his dying mother, Gwen. Her life is a grind, and like all the other women she toils with at the local chicken factory, is spent in service of the clock.

Helen lives only for laughing with her friends at work, caring for Gwen, and music. But when Joanne, the girl she secretly loved at school, returns to town, Helen's world is turned upside down. In the grand tradition of British working-class dramedies and filled with bursts of magical song, Chuck Chuck Baby is a film of love, loss and music set in and around the unlikeliest of places: a chicken factory in Industrial North Wales.
