Lovelorn Hannah Arterton turns up in Puglia for the wedding of her big sister (Annabel Scholey) and discovers that the groom is none other than her ex-holiday fling (Giulio Berruti).
Should she keep quiet and let the love of her life slip away?
Stand by for hits by the likes of Madonna, Wham!, Duran Duran and The Human League, belted out with teeth-rattling gusto by the cast.
Look out for pop star Leona Lewis and comedian Katy Brand as friends of the bride, and Greg Wise as her slimy ex.
The story and acting are about as subtle as a kiss-me-quick hat, but those in the right mood will find it irresistibly cheesy fun.
