The house is up for sale, but Sheila had had second thoughts. She decides to take in lodgers to help with the mortgage: Carol (a fellow art student of daughter Monica) and Chris (an unsuccessful DJ).

Sheila has a meeting with her bank manager who says that she faces repossession. To remedy this she takes in two more lodgers: Hamish (an airline steward) and Henry (a medical student). Her friend Richard agrees to stand as her guarantor.

Chris is unhappy that Hamish is moving into his room as he fears that Hamish is gay. Sheila gets fired from her job, but is hired by Richard to type his latest novel. Later, Hamish plays up to Chris's fears, much to his unease.

Sheila needs to pay her electricity bill and latest bank installment. Chris needs money also and attempts to sell his van. Sheila raises the money and he drives her to the bank. Her bank manager crashes into Chris's van and so he gains on insurance.

Hamish, a budding chef, cooks a meal for the housemates. Richard, eager to help Sheila financially, pays a woman to hire her typing services. Sheila is furious when she finds out, but they make up as they all enjoy Hamish's meal.

Chris gets a 'high profile' job as a male model. Carol falls for Henry, while Henry falls for Monica. Richard proposes to Sheila but she turns him down. Later, while watching TV, the housemates discover that Chris's modelling job was for a tacky advertisement.
