Back to Pontyberry in the South Wales Valleys for more laughs with hard-working, 40-something, single mum Stella and her unusual collection of family and friends. Stella is pregnant and worried: does she really love Sean - and is it even his baby? And son Luke is thousands of miles away in Canada - but for how long? Still, there's plenty happening in town to take her mind off things: Emma's trying her best to do the marriage thing but husband Sunil's being distracted by some extra-curricular activities. Nadine and Karl have set up a tanning salon, lollipop man Alan is being replaced by a pelican crossing, Dai and Paula have lost their mojo and teenager Ben has fallen in love! Then there's the arrival of eager-to-offend Aunty Brenda who tells it as it isn't, a Dutch new age therapist, Peschman Hodd and Alan's ex-wife Melissa who puts everyone on edge. But it's the return of Rob Morgan, Stella's ex and Luke's father, which really sets a cat amongst the Pontyberry pigeons, putting Stella in a right kerfuffle.
