On the night before the wedding, Peggy's boiler bursts. It's a disaster! But Pam comes to the rescue, insisting that the Arkleys move in with the MacDonalds for the night. Pam soon regrets her generous offer though when Jackie and Peggy make themselves a little too much at home.
The following morning all seems well until a freak accident results in a seething Pam stuck in A&E, a distraught Peggy locked in a bathroom and a desperate Leo waiting at the church for his absent bride. Is this the end of the road for the happy couple?
