Just north of London live Wendy, Andy, and their twenty-something twins, Natalie and Nicola. Wendy clerks in a shop, leads aerobics at a primary school, jokes like a vaudevillian, agrees to waitress at a friend's new restaurant and dotes on Andy, a cook who forever puts off home remodeling projects, and with a drunken friend, buys a broken down lunch wagon. Natalie, with short neat hair and a snappy, droll manner, is a plumber; she has a holiday planned in America, but little else. Last is Nicola, odd man out: a snarl, big glasses, cigarette, mussed hair, jittery fingers, bulimic, jobless, and unhappy. How they interact and play out family conflict and love is the film's subject. 生活既艰难亦美丽。甜蜜生活。生活是甜蜜的。生活就该如此。 温蒂（艾莉森·斯戴曼 Alison Steadman 饰）和丈夫安迪（吉姆·布劳德本特 Jim Broadbent 饰）结婚多年，两人育有两个女儿娜塔莉（克莱尔·斯金纳 Claire Skinner 饰）和尼古拉（简·霍洛克斯 Jane Horrocks 饰）。温蒂本分贤惠，操持着家中大大小小的事务，而安迪辛勤工作，希望有一天能够自立门户。 娜塔莉是一名水管工，个性开朗的她向往自由不羁的生活，喜欢和朋友们待在一起，然而，尼古拉却恰恰相反，有些神经质的她不仅整天紧张兮兮，还患有厌食症。尼古拉和男友之间的感情产生了裂缝，这让尼古拉的精神濒临了崩溃的边缘，与此同时，安迪在一次意外之中身负重伤，整个家庭的重担全部落在了温蒂和娜塔莉的肩头。
