Livia's been planning her wedding to Jed for ages. Now, at the venue in beautiful Barcelona, with her dress pressed and the guests all on their way, she's only left one tiny detail until the last minute: letting the groom know he's about to get hitched.

But as far as Jed's concerned, they've been bumping along just fine for ten years and even have a baby on the way, so why spoil things with an 'I do'? Especially when he'd really rather not.

Meanwhile the guests are arriving with plenty of baggage of their own. Fading reality star Liam's still on the lookout for a plus-one; Rachel's has refused to come--and dumped her into the bargain; and divorcee Patrick's date is more of the 'mid-life crisis' variety.

But as the ceremony approaches, and with no sign of Jed, there's only one thing on all of their minds: will there be a bride and groom at the wedding?
