The film Locke consists entirely of scenes of construction foreman Ivan Locke talking on his mobile phone while driving down a motorway on the day before he must supervise a large concrete pour in Birmingham.
Having learned that Bethan, a co-worker with whom he had a one-night stand seven months previously, has gone into premature labour, he decides to drive to London to be with her during childbirth, despite his job responsibilities and although his wife and sons are eagerly awaiting his arrival at home to watch an important football match.
Over the course of the two-hour drive, he phones his boss and a colleague to ensure that the pour is successful, phones his wife Katrina to confess his infidelity, phones Bethan to reassure her during her labour, and is fired from his job, kicked out of his house by his wife, and asked by his older son to return home. He also coaches his assistant Donal through preparing the pour despite several major setbacks, and has imaginary conversations with his father, whom he envisions as a passenger in the back seat of his car. As he finally reaches the hospital, Locke learns of the successful birth of his daughter.
