Maddie surprises Taylor by announcing she is engaged and planning to marry in two days' time (as you do...). To her horror, Taylor soon discovers that her sister’s new fiancé is in fact Raf, so she pretends she no longer has feelings for him and persuades him to keep their former romance a secret. Meanwhile, Doug arrives on the scene in pursuit of Maddie, and their entourage of friends -
including 2006 X Factor winner Leona Lewis and comedienne Katy Brand - join in the wedding preparations. Cue much questioning of the heart, some cheesy group dancing, slapstick humour and a chance to dress-up as 80s icons such as Adam Ant and Cyndi Lauper.
