Worried about the prospects of not being paid for the work they had done on Edith's cottage, Mack and Syd come up with an ingenious plan to get even with Marlon and Tricia. The cowboy builders pick the lock to The Woolpack and they find what they are after - the soon-to-be bride and groom's precious wedding cake. Marlon is horrified to realise the cake's been stolen, in its place is a plastic bride and groom with a ransom note from Mack demanding £7000. But when Marlon calls his bluff, Mack explains menacingly that the cake is only the start. Will the happy couple be forced to pay up, jeopardising their wedding? (thetvdb.com)
