Essie's mother, Celia (perfect wife and mother), discovers that her youngest is pregnant! This will not do. What is a mother to do?? Of course she turns immediately to the producers of the show. After all, they need to figure out a way to spin this story in order to save the show. Ideas are thrown around. Maybe a secret abortion? Perhaps they could cover up Essie's pregnancy and Celia could pretend to be pregnant. Oh wait - the best idea ever. Arrange a marriage (quickly of course) and of course the wedding would be broadcasted which would lead to ratings gold.
Naturally they picked option 3. It is a bit tricky though because Essie doesn't have a boyfriend. So they have to find someone willing to quickly 'fall in love' and marry Essie. Fortunately the show has a big budget so it's just a matter of finding someone in need of money.
