Mags Grimsdale and Julie Sultana are wedding planners. They rub along well but are as different as chalk and cheese. Mags is married to the love of her life, has four kids and a complicated extended family. Julie is impossibly glamorous, and doesn't remotely believe in love or marriage.
When Julie embarks on a life crisit, involving a hair-raisingly sexy fling with a much younger man, it is Mags who is left to pick up the pieces.
