Sarah Haywood is one of the most reputable wedding planners alive. She's spent the last 20 years creating some of the most elaborate and costly weddings in the world and knows that planning a wedding is a minefield. Because when it's supposed to be "the best day of your life" every single detail is loaded with significance.
Now Sarah is on a mission to help ordinary British couples as they navigate their own wedding planning pitfalls. With her inimitable, take-no-prisoners style, Sarah's on hand to mete out her no-nonsense advice and share her expertise, even - and sometimes particularly - when the couples feel they know best.
From an overstretched fiancee whose guests don't know they're coming to a wedding, to a detail-obsessed groomzilla whose husband-to-be can't spend another minute discussing how a ribbon should be tied, Sarah's experience is invaluable as she acts as mediator between stressed-out couples whilst making sure their expectations can be managed and met.
Along the way she has to deal with a strong-minded mother-of-the-bride who envisions a completely different kind of wedding from the happy couple and a busy twosome who want a highly ambitious and yet low-cost affair.
It's all in a (perfect) day's work as Sarah steers these "careering-towards-catastrophe" wedding plans in the direction of the exceptional celebration the couples are dreaming of.
