About that moment when you just have to telephone your mum. A documentary compilation of phone calls made by different people to their mothers. The film follows the lifespan of youth to adulthood, where a child changes from a dependant to a caretaker. The calls are interspersed with images of an old telephone exchange and electric wires, and the story of a young mother who doesn’t have her own mother to call. A film about a relationship that is intimate, painful and often slightly ridiculous.
