Tim Bisley and Daisy Steiner are two London twenty-somethings who meet by chance in a cafe while both are flat-hunting. Despite barely knowing each other, they conspire to pose as a young professional couple in order to meet the requisites of an advertisement for a relatively cheap flat, which is owned by and also houses the landlady, Marsha Klein. Also in the building is Brian Topp, an eccentric artist who lives in the ground floor flat. Frequent visitors are Tim's best friend, Mike Watt and Daisy's best friend, Twist Morgan.
