Tom Hepple, a geologist, and Gerri Hepple, a counsellor, are an older married couple who have a comfortable, loving relationship. The film observes them over the course of the four seasons of a year, surrounded by family and friends who mostly suffer some degree of unhappiness. Gerri's friend and colleague, Mary, works as a receptionist at the health centre. She is a middle-aged divorcee seeking a new relationship, and despite telling everyone she is happy, appears desperate and depressed. She often seems to drink too much. The Hepples' only child, Joe, is 30 and unmarried and works as a solicitor giving advice on housing.
