Does Mister Eleven always equal Mister Right? As her wedding day dawns, everything seems as perfect as it could be until numbers-obsessed maths teacher Saz Paley discovers that her perfect Mister Eleven is actually an imperfect Mister Ten! In this romantic comedy, Michelle Ryan stars opposite Sean Maguire and Adam Garcia in the story of a love triangle driven by irrational obsession and a belief that the best match for any British woman is her eleventh sexual partner. So what will become of Saz's new husband, the heart-throb Accident and Emergency doctor, and all round Mr Perfect, Dan? Will he be relegated from being Mr Statistically Right to Mr All Wrong? Will the handsome Aussie Alex who turns up at the wedding unexpectedly as an old friend's "plus one" become the new Mister Eleven? Or will Saz finally wise up and let true love take the lead over her numeric obsession?
