Set in the fictional Welsh town of Pontyberry, the series follows single mum of three Stella Morris and her friends and family.
Stella earns a living doing the locals' ironing. And, most of the time, she's relatively happy with life as she juggles the ups and downs of her family, amid the chaos of her eccentric friends, relatives and children's fathers. Her brood consists of eldest son Luke, a lovely boy who starts the series in prison as a consequence of joyriding; beautiful 16-year-old Emma who starts the series smitten with her first love Sunil and expecting his baby; and the brains of the family, 12-year-old Ben.
Stella's ex-husband Karl, father of Emma and Ben, has left her for new girlfriend Nadine but is involved in his children's lives. Luke's father Rob Morgan appears after 25 years, causing conflict for Stella who has recently started seeing 32-year old Sean. Stella's brother Dai is married to Paula, the local undertaker, and the two have a very kinky sex life. Paula's father, known only as "Daddy", and assistant Bobby help run Simpsons the funeral parlour. Stella's Aunty Brenda is the busybody of the town. And there's Alan, who has been in love with Stella since 1984 despite her just wanting to be friends with him.
New characters in the third series include Stella's new neighbour Michael Jackson (not that one).
Not to be confused with American TV Show of the same name.
Stella provides examples of the following tropes:
- Age-Gap Romance: The early-30's Sean and mid-40's Stella - it's one main reason they break up...that and the whole "she cheated on him" thing.
- The Alcoholic: Paula. Played for Laughs.
- Amicably Divorced: Stella and Karl. Stella is secretly pleased Nadine took him off her hands.
- Casual Kink: Paula and Dai.
- Celebrity Paradox

- Disappeared Dad: Rob Morgan, until Ben manages to track him down whilst doing a family tree project for school.
- Karl leaves for a new job in Abu Dhabi between the second and third series. He returns though in the last episode of the third series.
- The Ditz: Nadine, and to a lesser extent Emma.
- Eccentric Townsfolk: Just one example, the elderly couple who live across the road from Stella keep a horse. In their terraced house. She leaves him in Series 2 and takes the horse with her, but returns in Series 3 after Horse has died and they adopt a donkey... named Donkey.
- Estranged Soap Family: After Ken and Meg swap houses with Aunty Brenda in Tenerife, they fail to return for their great grandson's naming ceremony, or to support their son when his marriage begins to break down.

- One Steve Limit: Averted. Not only do we have Alan and his son, Little Alan, we also have two townsfolk called "Dai" - Stella's brother Dai Kosh, and rugby club chairman Dai Davies. A Running Gag is people having to specify which Dai they mean, even after Dai Kosh has left Pontyberry.
