Sarah helps Adam and Daniel as they prepare for what Adam hopes will be "the perfect wedding" in four months' time. Adam is a self-confessed perfectionist, while his Cuban fiancée Daniel is very laid back. When Sarah meets them, Adam is entering fully-fledged ‘groomzilla' mode, where his obsession with every tiny detail is at fever pitch.

Sarah has to put on her "counsellor" hat to keep the peace between the two grooms. To add to the stress, the couple are facing an anxious wait to see if Daniel's parents will get their visas to Britain in time to attend the wedding. Sarah has to dig deep to find a diplomatic way to navigate through such high expectations and even higher emotions.
