First of two programmes featuring jaw-dropping clips that show what happens when wedding events go awry. From proposals that do not turn out as expected to a best man given a 50,0000 pound surprise, weddings washed away by floods, hurricanes on honeymoons and how a bride's big day went up in smoke. The programme also reveals how the Queen became a wedding crasher, and how a bride gave her groom the surprise of his life at the altar.
