The hotly anticipated wedding of Iris Devonshire, ravishing teenage daughter of celebrity couple Mia and Leo, is to be held in the gardens of their grand Palladian pile alongside the Thames. But Mia and Leo worry that she's rushing into the marriage. Just ask their best friends since college, Simon and Laney de Montmorency, whose relationship is on the rocks again - and they've already married each other twice.

On the big day, Iris's hellraiser fiance Dougie Everett is not the only one flying high. As Iris rides up the aisle on a white stallion, a hot air balloon appears over the woods, heading straight for the ceremony. Its arrival is about to transform the lives and loves of some of the wedding guests for ever.

The Summer Wedding is a sizzling summer comedy set against the beautiful backdrops of the Chilterns, Spain, Africa and LA.
