Engineer Tom (Jim Brodbent Jim Broadbent) and counselor Gerri (Ruth Sean Ruth Sheen) are a middle-aged couple living in London. Single woman Mary (Leslie Manville Lesley Manville) is a colleague of Gerri. When Gerri invites Mary to dinner in the spring, Mary tells them that she is saving money to buy a car. That night Mary got drunk, spent the night at Gerri's house, and met Tom and Gerri's son Joe (Oliver Mortman Oliver Maltman) in the morning. In the summer, Mary finally bought a used car. She came to Gerry's house for a friend party and met Tom's old friend Ken (Peter White Peter Wight). However, the equally lonely Mary only panicked about Ken's courtship. In the fall, Joe brings his girlfriend Katie (Karina Fernandez Karina Fernandez) with him.
