Ruth Jones returns to the Welsh valleys as put-upon single mother Stella. Stella and Sean are preparing for their new arrival, while Emma is settling into married life with Sunil.

Stella feels destined to spinsterhood until Aunty Brenda arranges a job at the Bap Factory to bake away the blues. Her first day soon takes an unsavoury turn, though. Elsewhere, Britain's favourite ballroom-dancing astrologer Russell Grant sweetens the mood at Nadine and Karl's salon opening.
