It's Luke's 25th birthday, and while Stella is all loved up with Sean, the birthday boy doesn't know what to do about the return of his father, Rob Morgan.
Stella couldn't be happier: she's all loved-up with Sean and it's Luke's 25th birthday, providing the perfect excuse for a good old-fashioned knees-up. She's even off to the hairdressers in honour of the party of the century. But first, she fancies her hand at boxing and has Sean show her a few moves. And when a surprise visitor drops in at Big Ray's, Stella soon finds herself in the ring with a Welsh boxing legend - although a practical joke leads to a close shave when Sean receives a killer blow.
While Stella is gearing up for Luke's party, the birthday boy is harbouring a secret. Having met with his estranged father, Rob Morgan, he is unsure about whether he wants to get to know him. Rob, on the other hand, wants to make up for lost time.
At the party, spirits are high and the booze is flowing. As Alan tries his best to shake an admirer, Jasminder tries her hardest to impress Luke, and Stella and Sean share a romantic moment on the dance floor. But an unexpected guest soon brings the celebrations to a dramatic halt...
