Laura and Jamie are struggling to cope with the everyday challenges of raising their baby, so the last thing they need is a big family event. But the christening is looming and they are nowhere near ready for it.
Mike is desperate to prove himself worthy of being a godfather, much to atheist Beth's irritation. But Mike has got stiff competition from Jamie's cousin Conall, a trainee priest.
Keith, under pressure from Sandra, is forced to take temping work at the toy shop to help pay for the christening. But Keith finds it hard to cope when he discovers his new supervisor is his son.
All is not well with Laura's family either. Janet is trying to put a halt to the christening, which she feels will bring public shame on the family. Part of Laura would like the whole christening to go away too, but Jamie, under pressure from his family, is saying they can't back out.
Alan is still recovering from his head injury, so Janet wants to go back to work, although she's not mentioning this to Alan.
As the visiting relatives arrive, squabble and then criticise, Jamie and Laura are really feeling the pressure - and they haven't even managed to agree on a name yet.
